# How do you simplify (6.3times10^15)/(2.1times10^11)?

Aug 1, 2016

$\frac{6.3 \times {10}^{15}}{2.1 \times {10}^{11}} = 3 \times {10}^{4}$

#### Explanation:

$\frac{6.3 \times {10}^{15}}{2.1 \times {10}^{11}}$

= $\frac{6.3}{2.1} \times {10}^{15} / {10}^{11}$

Now as $6.3$ is divisible by $2.1$, dividing we get

$\frac{3 \cancel{6.3}}{1 \cancel{2.1}} \times {10}^{15 - 11}$

= $3 \times {10}^{4}$
