ratelena [41]

Answer:

$2.7 * 10^{4}$

Step-by-step explanation:

Given the expression $\frac{8.9*10^{8} }{3.3*10^{4} }$ , to express the the fraction in scientific notation, we will apply the law of indices below;

According to one of the laws of indices, $\frac{a^{m} }{a^{n} } = a^{m-n}$

Applying this to the fraction;

$= \frac{8.9*10^{8} }{3.3*10^{4} }\\\\= \frac{8.9}{3.3} * \frac{10^{8} }{10^{4} }\\\\ = \frac{8.9}{3.3} * 10^{8-4}\\\\ = \frac{8.9}{3.3} *10^{4}\\\\ = 2.697 * 10^{4}$

The best estimate for the fraction in scientific notation will be $2.7 * 10^{4}$
