Problem
What is the value of 
$\textbf{(A)}\ -125\qquad\textbf{(B)}\ -120\qquad\textbf{(C)}\ \frac{1}{5}\qquad\textbf{(D)}}\ \frac{5}{24}\qquad\textbf{(E)}\ 25$ (Error compiling LaTeX. Unknown error_msg)
Solution
$(2^{0} - 1 + 5^{2} +0)^{-1} \ctimes{} 5 = (1 - 1 + 25 +0)^{-1} \ctimes{} 5 = (25)^{-1} \ctimes{} 5 = \frac{1}{25} \ctimes{} 5 = \boxed{\frac{1}{5}}$ (Error compiling LaTeX. Unknown error_msg)
