May 31, 2015

The answer is $6.59 \cdot {10}^{7}$ m.

You have $65900000$ m.

In scientific notation, you'll have something like $6.59 \cdot {10}^{x}$ m.

Basically, you have to find by what number (a power of ten) you need to multiply $6.59$ to have $65900000$.

$6.59 x = 65900000$
$x = 10000000$
$x = 10 \cdot 10 \cdot 10 \cdot 10 \cdot 10 \cdot 10 \cdot 10 = {10}^{7}$

Therefore, $65900000 = 6.59 \cdot {10}^{7}$ m.
