## Problem

What is $\frac{2^3 + 2^3}{2^{-3} + 2^{-3}}$?

$\textbf {(A) } 16 \qquad \textbf {(B) } 24 \qquad \textbf {(C) } 32 \qquad \textbf {(D) } 48 \qquad \textbf {(E) } 64$

## Solution

We can synchronously multiply ${2^3}$ to the polynomials both above and below the fraction bar. Thus, $$\frac{2^3+2^3}{2^{-3}+2^{-3}}$$\

$\=\frac{2^6+2^6}{1+1}={2^6}$ (Error compiling LaTeX. ! You can't use a prefix with \endgroup'.)`

, which can be calculated resulting in 64. Therefore, the fraction equals to $\boxed{{64 (\textbf{E})}}$.
