Answer
$2.914\times10^{-6}$
Work Step by Step
Using the laws of exponents and the concepts of scientific notation, the given expression, $
(4.7\times10^{5})(6.2\times10^{-12})
$, simplifies to
\begin{array}{l}
(4.7)(6.2)\times10^{5+(-12)}
\\\\=
29.14\times10^{-7}
\\\\=
2.914\times10^{-6}
.\end{array}
