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 $\{2^3}$ (Error compiling LaTeX. Unknown error_msg) to the polynomials above and below .nickels and 7 pennies. Therefore, Leah has $6\cdot5+7=\boxed{64 (\textbf{E})}$ .
