\(2^{16}\) is
A. 2 more than \(2^{15}=2^{15}+2\)...No
B. 16 more than \(2^{15}\)=\(2^{15}+16=2^{15}+2^4\)...No
C. 1/2 of \(2^{32}=\frac{2^{32}}{2}=2^{31}\)..No
D. 2 times \(2^8\)=\(2*2^8=2^9\)
E. 2 times \(2^{15}\)=\(2*2^{15}=2^{16}\)....Yes

NOTE: this is one of those questions that require us to check/test each answer choice.
In these situations, always check the answer choices from E to A, because the correct answer is typically closer to the bottom than to the top.
For more on this strategy, see my article: https://www.gmatprepnow.com/articles/han ... -questions
E. 2 times \(2^{15} = (2)(2^{15})= (2^1)(2^{15})=2^{16}\) Bingo!!
Answer: E
Cheers,
Brent
