phi
  • phi
use the property log(a) + log(b)= log(a*b) (if the logs have the same base)
phi
  • phi
once you combine the two logs into one log, you have the same problem as some of the others. solve by making each side the exponent of the base 3

x = 81?
phi
  • phi
yes. Is the process clear how to solve this one ?
phi
  • phi
we could solve this one a different way, because we know log_3 (3) = 1 (normally we cannot do the log in our head) so the problem is 1+log_3(x) =5 add -1 to both sides log_3(x)= 4 make each side the exponent of 3 (this gets rid of the log) x = 3^4 = 81
