Solve for x: 2^(x+4) = 4^(x-2) A. 0 B. 1 C. 4 D. 6 E. 8

Answer 1

Because this gives you multiple choice, you can just plug in all the numbers given and try them. 
A: Since this says that x equals 0, you would get 16 isn't equal to 1
B: Since this says that x equals 1, you would get 32 isn't equal to .25
C: Since this says that x equals 4, you would get 256 isn't equal to 16
D: Since this says that x equals 6, you would get 1024 isn't equal to 256
E: Since this says that x equals 8, you would get 4096 IS equal to 4096

So E is CORRECT!!
