Question

What is the solution to 4log4(x+8)=4^2

Answer 1

The answer is 8.

Explanation:

Just took the test and it was correct.

Answer 2

x=248

Explanation:

4log4(x+8)=4^2

Divide each side by 4

4/4log4(x+8)=4^2 /4

log4(x+8)=4

Using logb(x) = a yields b^a =x

4^4 = x+8

256 = x+8

Subtract 8 from each side

256-8 = x+8-8

248 =x
