Question

(1) Write log9+1/3log729 as a single logarithm.

(2) Write log[2]5-1/2log[2]169 as a single logarithm.

anonymous · Answer

1) the 1/3 would just be the exponent of log(729) so log(729)^1/3 and then we use log rule log(ab)= log(a)+log(b) to get log(9)(729)^(1/3)

anonymous · Answer

log(6561)^(1/3)

anonymous · Answer

so i solve that? @jbovey  i got In9/in10

anonymous · Answer

is that for the #(2)?

anonymous · Answer

no thats the answer for #1. Since it says just write as single log you wouldn't have to solve any further

anonymous · Answer

it just wants you to use the log rules and combine

anonymous · Answer

oooh ok.. so what about #2?

anonymous · Answer

Im kind of confused by the way you wrote it. Can u draw the equation out so I can see?

anonymous · Answer

yupp! hold on..

anonymous · Answer

I know you'll have to use log rule 3 which is log(a)-log(b)= log(a)/(b)
