If $2 \times 10^{3}$ is represented as $2 E 3$ on a certain calculator, how would the product of $2 E 3$ and $3 E 2$ be represented?
(A) $6 E 6$
(B) $6 E 5$
(C) $5 E 5$
(D) $2.3 E 3$
(E) $5 E 6$
Solution

The product of $2 E 3$ and $3 E 2$ is $\left(2 \times 10^{3}\right)\left(3 \times 10^{2}\right)=6 \times 10^{5}$, which can be written as $6 E 5$.
