Jun 6, 2017

$\left(3.4 \times {10}^{4}\right) \left(7.2 \times {10}^{- 15}\right) = 2.448 \times {10}^{- 10}$

#### Explanation:

$\left(3.4 \times {10}^{4}\right) \left(7.2 \times {10}^{- 15}\right)$

= $\left(3.4 \times 7.2\right) \times {10}^{4} \times {10}^{- 15}$

=$24.48 \times {10}^{4 - 15}$

= $24.48 \times {10}^{- 11}$

= $2.448 \times 10 \times {10}^{- 11}$

= $2.448 \times {10}^{- 10}$
