Evaluate by using scientific notation and the laws of exponents. Leave you answer in scientific notation.
-$$\frac { ( 0.00032 ) ( 0.0002 ) } { 0.0008 }$$
A) $8 \times 10 ^ { - 5 }$
B) $64 \times 10 ^ { - 6 }$
C) $8 \times 10 ^ { 5 }$
D) $64 \times 10 ^ { 6 }$

First, convert each number to scientific notation: $0.00032 = 3.2 \times 10^{-4}$, $0.0002 = 2 \times 10^{-4}$, $0.0008 = 8 \times 10^{-4}$. Then, $\frac{(3.2 \times 10^{-4})(2 \times 10^{-4})}{8 \times 10^{-4}} = \frac{6.4 \times 10^{-8}}{8 \times 10^{-4}} = 8 \times 10^{-5}$.
