Remove the parentheses and take out the constansts.

$(7 x 3) x^{2} x^{5} y^{3} y^{8}$

Answer:

A. -18·10^6

Step-by-step explanation:

The rules of exponents apply to powers of 10 used in scientific notation. The associative and commutative properties of multiplication also apply.

<h3>Application</h3>

(a^b)(a^c) = a^(b+c)

The numerical product is ...

$(9\cdot10^9)\cdot(-2\cdot10^{-3})=(9)(-2)(10^{9-3})=\boxed{-18\cdot10^6}$

<em>Additional comment</em>

Expressed in scientific notation, the result would be ...

$-1.8\cdot10^7$

Your calculator can perform this multiplication for you.
