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

jim_thompson5910Best ResponseYou've already chosen the best response.1
what rule is used next?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
read the rules carefully

iheartfoodBest ResponseYou've already chosen the best response.1
sorry rule #1? cuz its + ?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
we used rule 1 to get log(10^5) + log(x^3)
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
ohhh then idk :( I'm confused :(
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
read the rules again and look at the examples
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
okay so i am looking for the rule that solves log(10^5) + log(x^3) ??
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
you're looking for a rule that can simplify that yes
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
okay so do i use rule #3??
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
idk, is that right? rule 3?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
yep, that allows you to pull down the exponents
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
okay so how do i solve from there? I'm still a bit lost :(
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
ex: rule 3 says we can go from log(10^5) to 5*log(10)
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
ohh okay so i get this? log(10^5) + log(x^3) = 5log(10) + 3log(x) ??
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
which then =5+3log(x) so my answer is D?? is that right? :O
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
the log of 10 is 1 (since log is default base 10)
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
okay so if i have 6log(10) my answer is 6?
