log4 (x - 3) + log4 (x + 3) = 2 @Mathematics

Answer 1

Sorry didn't put this in***
Solve for x. Check for extraneous solutions...

Answer 2

(x-3) *(x+3) =x^2-9
so log (base 4) x^2-9=2
is the smase the base^2
so 16=x^2-9
25=x^2
x=5
heres why
x = b^y is the same as y = log(base b)x

Answer 3

or x=-5 cause square root of a # could be negative

Answer 4

Oops sorry it not log4 it ....
