Question 29879: Find all real solutions of the following equation:log[4]x+log [4] (x+12) = 3
Here are the possible solutions:
(1) x=12
(2) x=4
(3) x= 16,12
(d) none of these

Answer by Cintchr(481) (Show Source): You can put this solution on YOUR website!
log[4]x+log [4] (x+12) = 3 when adding, you are really multiplying
log[4](x)(x+12) = 3
log [4] (x^2 + 12x) = 3
[4] is the base
3 is the power
x^2 + 12x is what they equal
