What do these expressions mean in English?
1.

Nathan B and Flybaby13 have it right.... other answers for #1 are wrong...that's another expression "she got under my skin" usually means that "she annoys me in some way"...these aren't the same expressions
Can you help me condense this logarithmic expression?
First of all, subtraction of logarithms on the same base is the same as the logarithm of the quotient: [math]3log_b5 = log_b(\frac{4}{y})[/math]then, we know that x*log(y) = log(y^x) [math]log_b 5^3 = log_b[/math][math](\frac{4}{y})[/math]the two logarithms are the same if and only if their arguments are the same. Remove the logs! [math]125 = \frac{4}{y}[/math]And now simply solve for y. [math]y = \frac{4}{125}=0.032.[/math]
Can you help me with this JAPANESE expression ?
Well, you seem to be aware that wakannaku is just a slangish version of wakaranaku. Nachau comes from "naru" wanaranaku naru (lit: to become "not understanding" of...) (Adverbial form + naru = to become something) Nachau is a slangish form for: Natte shimau. Te form + shimau expresses things that are completely done, especially regretful things. Literally, it says something like "I will regretably become ununderstanding of it")
What are colloquial expressions?
Colloquial expressions are informal words, phrases, and sentences that are generally more appropriate for spoken conversations than for written essays So, basically slang... for example, to great your friends you might say: "Hey guys!" but to great your teacher you might say "Hello, sir." Or you might say "red up your room" to your friend, but their parent would say "you should really clean your bedroom" @deb: lol u have an awesome grandma!

Can you help me write a Regular Expression (regex) for a phone number?
/2567\d{8}/Well, to be honest, the actual regular expression will vary a little by the exact regex engine you are using (some don’t need the surrounding slashes, for example), but for the most part, that is really all there is to it. You spell out the characters that you know, and specify that the rest of the string is 8 (the bit in the braces) consecutive digits (the \d class).
Can you help me translate this Japanese expression?
"-te + oku" is a set expression. Oku means "in advance", "for future purpose" Please have a look at the grammar guide of Kim Tae.

Please scroll down to -te oku ておく もらえる物は、もらえるとしたら, もらっておくか Moraeru mono wa, moraeru to shitara, moratte oku KA (The last syllable is ka not wa) Things that I can get, in case I can get them, shall I get them (and keep them for future purpose)?
Can someone help me simplify these rational expressions?
In general, the strategy is to factor out the equation- I’ll do #9 as an example, and it should help you understand.In general, a quadratic equation will be comprised of 3 parts:[math]a(x^2)+bx+c[/math]The solution is to find the two pairs of numbers that look like[math]dx+e [/math]and[math]fx+g, [/math]such that:[math]a = d*f[/math]b = e+g c[math] = e*g[/math]In this case, [math]a(x^2)+bx+c [/math]has:[math]a = 1[/math][math]b = -6c = -27[/math]So, what can we learn from this? Well, a = 1, and the only (integer) combo of numbers with a product of [math]1[/math] is [math]1 [/math]and [math]1. [/math]So far, we know this much about our pairs:[math]1x+e[/math][math]1x+g[/math]So, the next question: What combo of numbers sum to -6, but have a product of -27? We know at least one must be negative number, since that is the only possible way to have a negative sum or product. Temporarily ignoring that, its more important to focus on b being 6. That means g and e have a difference of 6. So, a factor list of 27 looks like this:[math]1,27[/math][math]3,9 [/math]The only pair with a difference of 6 is 3 and 9, so that must be our pair. The last question is which one is negative? C doesn’t tell us anything, either one could be negative. B however, tells us that the larger of the two is greater. Based on all this, our combo looks like:[math](x+3)*(x-9).[/math]Following the same logic, the denominator looks like:[math](x+6)*(x-9)[/math]In order to simplify these expressions, we remove [math](x-9)[/math] on top and bottom. We’re left with the final result, and we’re done!(And a small hint I’m not sure if you need or not, but if there is no bx or c or a(x^2), then that means a or b or c is [math]0[/math].)
Could you English help me understand this expression?
I am a speaker of English which doesn't quite make me English, but I understand your meaning. This exercise is a prime example of getting to know a language all the way to its heart, not merely superficially. Learning tons of words and mounds of verb declensions will not prepare the faint of heart for the nuances of the new language. Learning Spanish, I learned that to express that one overslept you say, Se me pegaron las sabanas. Literally, The bed sheets stuck to me! I learned that from an Aruban many years after I espoused Spanish. The inference of the phrase in parentheses is that you have to keep current in what your friends are up to (sorry, an Englishism, I think), rather, what your friends are saying and doing. A few years ago, our creative writing instructor entered the class with a puzzled look on his face and told the class, I don't understand this, can somebody help me with this? All of us leaned forward, eager to help, curious as to our instructor's bewilderment. He said, I just got a text message on my cell phone from a young friend and he closed by saying Hit me back on the hip. I don't know what he meant. I smiled as the others looked as perplexed as the instructor and I then said, He means for you to text him or call him back on his cell phone. Everyone was startled that I had broken the code. It seemed natural enough to me, having heard a lot of conversations amongst teens and young adults. Hit me back was the common phrase for call me back or communicate with me, and on the hip is where most people carry their cell phones! Mystery unraveled. Amazing. We speak the same language, so differently, no? Yes!
How do you solve these logarithmic expressions?
#1 log2(32) = 3x. This can be rewritten as 2^(3x) = 32. *The problem you ran into when you solved it was saying that 2^3x = 8x. It can't be simplified this way.* We can rewrite 32 as 2^5. Then we have 2^5=2^3x. So, 5=3x. x=5/3. #2 log3(2c)=-2. Like last problem, this can be rewritten as 3^(-2) = 2c. 3^(-2) = 1/9. If 1/9 = 2c, c=1/18. #3 This one is way easier than it looks. If log4(3x-1)=log4(2x+3), then (3x-1) = (2x+3). Subtracting 2x from both sides, x-1 = 3. So x = 4.
