Please tell me if this is right...
Solve the logarithmic equation:
log_4(x18) + log_4 (x3) = 2
log_4((x18)(x3)=4^2
x^221x+54=16
x^221x+38=0
(x2)(x19)=0
x=2, x=19 < Answer

Best ResponseYou've already chosen the best response.1your final answer is correct but the 2nd step will be log_4((x18)(x3)=2 then 3rd step x^221x+54=16 is correct

Best ResponseYou've already chosen the best response.1or your 2nd step could be log_4((x18)(x3)=log_4 (4^2)

Best ResponseYou've already chosen the best response.0yea I did that but I skipped the step on here. I wrote that on my paper.

Best ResponseYou've already chosen the best response.1oh, wait i just realized, x=2 cannot be the answer

Best ResponseYou've already chosen the best response.1because that would make x3 as negative then log (x3) will not be defined @Fakshon
