answer choices A,B,C,D from top to bottom :)

here are the log rules you will use

http://www.purplemath.com/modules/logrules.htm

kk :)

use rule #1 to break up the expression to get
log(10^5) + log(x^3)

what rule is used next?

umm, idk rule #2?

read the rules carefully

sorry rule #1? cuz its + ?

we used rule 1 to get log(10^5) + log(x^3)

ohhh then idk :( I'm confused :(

read the rules again and look at the examples

okay so i am looking for the rule that solves log(10^5) + log(x^3) ??

you're looking for a rule that can simplify that yes

okay so do i use rule #3??

idk, is that right? rule 3?

yep, that allows you to pull down the exponents

okay so how do i solve from there? I'm still a bit lost :(

ex:
rule 3 says we can go from log(10^5) to 5*log(10)

ohh okay so i get this?
log(10^5) + log(x^3)
= 5log(10) + 3log(x)
??

keep going

which then =5+3log(x)
so my answer is D??
is that right? :O

the log of 10 is 1 (since log is default base 10)

yep

okay so if i have 6log(10) my answer is 6?

and yay!! :)

yep

kk thanks!!

kk thanks!!
