Kendall Lyons · Answer 1

2^ (x + 3) = 512

ln (2^ (x + 3)) = ln (512)

(x + 3) ln (2) = ln (512)

ln (2) ln (2)

(x + 3) ln (2) = ln (2^9)

ln (2) ln (2)

(x + 3) ln (2) = 9ln (2)

ln (2) ln (2)

x + 3 = 9

- 3 - 3

x = 6

Gloria Hunt · Answer 2

X=1, the equation=16; x=2, the equation=32; by such analogy, when x=6, the equation=512. so the answer is x=6.
