5$x , e , y = x \cdot 10^y$. – PhoemueX May 02 '16 at 20:46

\begin{align} 5e2 & = 5\times 10^2 = 500 \\ 5e{-2} & = 5\times 10^{-2} = 0.05 \\ -5e2 & = -5\times 10^2 = -500 \\ -5e{-2} & = -5 \times 10^{-2} = -0.05 \end{align}

Plese type your answer and use MathJax to render the math instead of pictures that aren't searchable. Thank you. – user577215664 Sep 19 '20 at 04:18
