Write 29,678,900,522 in scientific notation

The goal of writing a number in scientific notation is to have a decimal number, with one digit to the left of the decimal point, followed by a × 10 to some power.To format your number in this way, we'll divide the 2967890052 by 10, 9 time(s), making it a 2.96789.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 109 next to the 2.96789.So, the final answer is 2.96789 × 109
