Q: Dish soap, warm running water, and a soft sponge are all you'll need for regular cleanings. Basic, routine cleaning is the same for all copper sinks, whether your sink is vintage, hammered, raw, or polished. Use only a soft, non-abrasive sponge or cloth. Don't use harsh scrubbers, such as steel wool. Run warm water from the faucet and use the sprayer to wet the sink. Squirt one or two drops of the dish soap onto the wet sponge. Wipe down the sink with the soapy sponge from top to bottom on all sides. You should clean your sink daily to keep it in the best shape. Use the sprayer to rinse away soap suds with warm water. After thoroughly rinsing the sink, dry it with a clean towel. Drying the sink will prevent the formation of mineral deposits and green spotting. To remove a stubborn mark or stain, apply baking soda to a cloth and, with warm water running, gently scrub the affected area. If your sink is shiny and polished or finished, you can add vinegar to the baking soda to remove a stain. However, if your sink is vintage or you want to preserve a patina, avoid using vinegar.
A: Use a mild dish soap and a soft sponge to clean your sink. Wipe all sides of the sink with the soapy sponge. Rinse and towel dry the sink after cleaning it. Use a baking soda paste for stubborn stains.

Q: There are many reasons you may have forgotten a password in the first place. For one, it may have been thought up on the spot, or you might have made it too complex to remember in full. While making your password hard to guess is an essential security step, the most important thing about a password is how uniquely memorable it is to you. Thinking up a distinctive, but memorable password can be difficult, as obvious answers (like the name of a place or person) are too easily guessed.  Try combining a few individually memorable words. For instance, your pet's name is a weak choice on its own, but pairing it with something completely unrelated, like your favourite food or comic book character, is a strong way to send hackers for a loop. When you're making a password, most sites will have an indicator that tells you how strong your password is. While these are vague tools at best, you'll want to aim for an average strength at least. Adding symbols and numbers to your code is a smart way to improve security. Another common trick you can use is to invent a mnemonic acronym. Write the first letter of each word of a memorable sentence, thereby creating a gibberish word. For example, the sentence "Friday is my favourite day of the week" would become 'Fimfdotw'. Likewise, "Free jazz is my favourite kind of music" would become 'Fjimfkom'. This can be applied to virtually any sentence imaginable, so long as it has enough words to satisfy the password's minimum character count-- usually 8. While you should write passwords you'll be able to remember reasonably well, you should write down your passwords and put them somewhere safe if you think there's a chance you'll forget them again. Seal the envelope, and leave it unmarked, or mark it as something misleading. That way, if someone manages to find it, they won't likely grasp its importance. If you're really concerned that you'll lose the envelope, you might consider giving the envelope to a trusted friend or a loved one. This is not recommended however, as it means giving up the sole control over your passwords and, by extension, your personal information. Especially if you're using different passwords for each of your various accounts, you might find them difficult to keep up with on your own. Fortunately, there is password management software available that will fill in the data for you. On the downside, most password managers available cost money-- generally between 20 and 40 US dollars. However, you may find the added security worth it if you're worried about forgetting or the risk of being hacked.  Because a password manager essentially does the legwork of password for you, you can afford to have more complex passwords without worrying about remembering them yourself. As a free alternative, you could create an encrypted file on your computer with all of your passwords on it. That way, you'll only have to remember one of them off the top of your head. It goes without saying that passwords for banking information should be treated with greater weight than the password for your avant-garde jazz blog, but as a general rule, you want to make your passwords more difficult to crack depending on how important the account is to your life and well-being. At the same time, while byzantine symbols or numbers can make a password harder to guess, it can also make them harder to remember. The trick is to strike a balance between complexity and memory. Don't write a password you don't think you'll be able to remember on a whim, and if you do, make sure to keep it written down on paper somewhere it does not stand any chance of getting misplaced or seen by someone else.
A: Make an effort to come up with a memorable password. Write your passwords and keep them in a sealed envelope. Use a password manager. Take your passwords as seriously as the information they're meant to protect.

Q: If your expression is not already set up like a fraction, rewrite it this way. This makes it easier to follow all the necessary steps when dividing by a square root. Remember that a fraction bar is also a division bar. For example, if you are calculating 144÷36{\displaystyle {\sqrt {144}}\div {\sqrt {36}}}, rewrite the problem like this: 14436{\displaystyle {\frac {\sqrt {144}}{\sqrt {36}}}}. If your problem has a square root in the numerator and denominator, you can place both radicands under one radical sign. (A radicand is a number under a radical, or square root, sign.) This will simplify the simplifying process. For example, 14436{\displaystyle {\frac {\sqrt {144}}{\sqrt {36}}}} can be rewritten as 14436{\displaystyle {\sqrt {\frac {144}{36}}}}. Divide the numbers as you would any whole number. Make sure to place their quotient under a new radical sign. For example, 14436=4{\displaystyle {\frac {144}{36}}=4}, so 14436=4{\displaystyle {\sqrt {\frac {144}{36}}}={\sqrt {4}}}. , if necessary. If the radicand is a perfect square, or if one of its factors is a perfect square, you need to simplify the expression. A perfect square is the product of a whole number multiplied by itself. For example, 25 is a perfect square, since 5×5=25{\displaystyle 5\times 5=25}. For example, 4 is a perfect square, since 2×2=4{\displaystyle 2\times 2=4}. Thus:4{\displaystyle {\sqrt {4}}}=2×2{\displaystyle ={\sqrt {2\times 2}}}=2{\displaystyle =2}So, 14436=4=2{\displaystyle {\frac {\sqrt {144}}{\sqrt {36}}}={\sqrt {4}}=2}.
A:
Set up a fraction. Use one radical sign. Divide the radicands.  Simplify
