Math Help? pls? 3
1.Express as a single logarithm.
3logb c - logb a (the b is the little letter after the log)
2. Express as a single logarthm and simplify.
1/2log2 16 - 2log2 4 (the 2 after log is the tiny one)

lol u seem terrible at logs
how do you not know what the exponent sign is by this point in your math career, and not be able to apply log rules
[quote=sparkshooter]Lol don't worry, logs are a commonly hated topic, I'm one of the very few people on earth that love them.[/quote]
Then I'm part of that too. Everyone hated log in my class, but for some reason, I actually liked it.
It was like theorems in geometry. Most hated concept in the class. But I kinda thought it was ok.
[quote=hgvd]I think it's an interesting concept.
Besides math, we use it inchemistry to find pH/pOH so using log is pretty interesting[/quote]
Yeah, my strength is anything Algebra related. If it has an equals sign, I will probably love it.
I absolutely detest trigonometry with a passion though.
Yeah, I think I remember that in Chemistry. I was horrible at that course.

[quote=2DayiDual]why did u square the 16 instead of halfing it?
actually nvm i feel stupid[/quote]

Fractions on Basil are a real hassle, so I screenshotted my work on Microsoft Word:

[quote=2DayiDual]what does ^ stand for and thanks! [/quote]
"To the power of"
Exponent
It means to the power of.

Do you know the rules? I'll just give them to you.
log(a) + log(b) = log(ab)
log(a) - log(b) = log(a/b)
b*log(a) = log(a^b)
You should try it now, it's pretty simple. If you don't understand, feel free to ask.
EDIT: Actually, I'll just do it.
3logb(c) - logb(a)
logb(c^3) - logb(a)
logb(c^3/a)
