Nov 27, 2017

$\left(0.08 {x}^{11}\right)$

#### Explanation:

Multiply it together - multiply whole numbers with whole numbers and exponents with exponents.

Exponent product rules explains when multiplying exponents, add exponents together. $\left({a}^{n} \cdot {a}^{m} = {a}^{n + m}\right)$

$= \left(0.8 {x}^{9}\right) \cdot \left(0.1 {x}^{2}\right)$
$= \left(0.08 {x}^{11}\right)$
