Question

express 6.66 x 10^(-2) hectometers in meters. round your answer to 3 significant figures. if the answer is too large or small put your answer into standard scientific notation.

Explanation:

Step1: Recall conversion factor

1 hectometer = 100 meters.

Step2: Convert the given value

$6.66\times10^{-2}$ hectometers $\times100$ meters/hectometer = $6.66\times10^{-2}\times10^{2}$ meters.
Using the rule of exponents $a^{m}\times a^{n}=a^{m + n}$, we have $6.66\times10^{-2 + 2}=6.66\times10^{0}=6.66$ meters.

Answer:

$6.66$
