What is the product of 3.6•10^9 and 7.35•10^5?

il63 [147K]

The answer is very simple to get if you have a calculator. You first multiply $3.6$ and $7.35$ . You should get 26.46, now you move one decimal to the front which means you are multiplying 10 to it. Now you can refer the rest from below:

$2.646 * 10^{1} * 10^{9} * 10^{5}$ Add the powers of ten
$2.646 * 10^{1+9+5}$
$2.646 * 10^{15}$ This is your answer =)
