Best sign that you've improved: making someone rage about your class as hard as this loud-mouthed heavy does by Nordvargrin tf2

Holy hell, I was on your team during this match playing Pyro. Sac77. That's incredible.

The game-winning pitcher in 17 innings... by BalooDPin baseball

[–]dubsac012 10 points11 points ago

Chris Davis grew up 20 minutes away from me and had to change high schools in order to start on the baseball team. Here he is now striking out 5 times and becoming the winning pitcher in the same game. AND tearing Aaron Cook's leg up the day before. All in a series. Absolutely stunning to see.

You guys know what he means. Obviously these girls lead a life of debauchery and only use religion as a crutch to get more likes on Facebook statuses. Really not hard to see these girls left and right. Not even being cynical.

Thanks Paul. I really appreciated the help.

Sorry for the wait between replies. I passed out early last night.

On 20, I've expanded it to ln x1/3 - ln y1/3

On 21, I've expanded it to log_7 x2 - log_7 y2

Thanks man!

Actually, 1/3 ln x- 1/3 ln y and 2 log_7x- 2 log_7y

Ah, sorry about the parentheses. I should have been thinking in terms of how I'd input it in a calculator.

I see what you did on 27, using log_b(xa) = a log_b(x). I guess that just didn't phase me.

On 28 I was trying to divide out x2- 4 and x-2, but now i'm seeing all i had to do was change it using the same principle I've been using, lol.

I really do appreciate the help, man.

I guess, since the other page isn't loading, could you explain how I'd "Use the properties of logarithms to expand the expression as a sum, difference, and/or constant multiple of logarithms" on questions 20 and 21. 20. ln cube root(x/y) 21. log_b(7)(x/y)2

Edit: Also, how do you get out of superscripts when doing powers? e.g. x2-4 when I want to put x2 -4

Can you not read the top page? Or is it not loading? Either case

Thanks for the help. I have sort of a grasp on the subject, but I really needed these rules written out like you did.

Using that, I see that 24 and 25 need to be solved with just division and multiplication. I ended up with log_e(3.3375) and log 2.

On 26, I used log_b(xa) = a log_b(x) to change 2 log_b(2)(x-16) to log_b(x-16)2. I'm unsure if I should continue it to log_b(x2 -32x+256) or if I'm missing another step altogether.

On 27, using order of operations, i have (I think) log(x)/3 log(y)+4 log(z). If I multiply 4 log(z) by 3 log(y) I get log(x)+12 log(zy), then multiplying by log(x), 12 log(zyx). Is that correct?

On 28, I start with 2 log_e(x2 -4/x-2) which turns into 2 log_e(x/-6). I'm not sure if I should continue due to e being there, but using log_b(xa) = a log_b(x), I ended up with log_b(x/-6)2. I doubt that's right, but natural logs confuse me. I don't think our teacher has actually taught us that e has a value yet, let alone getting us to remember the number.

I've written on #s 11,12,15,16,17,22, and 23 in case it's hard to differentiate between my teacher's handwriting and my own.
