Question 1195847
 log27 base 3 + log 9 base 3 - log243 base 3


{{{log(3,27)+log(3,9)-log(3,243)}}}


You know some numbers in exponential form?

{{{log(3,3^3)+log(3,3^2)-log(3,3^5)}}}

You know some rules about log of exponentiated numbers?


{{{3*log(3,3)+2*log(3,3)-5*log(3,3)}}}

and the rest should be obvious...
