Question

How will you write this in scientific notation? if you do not mind explaining how you did it. Thank you!

$15,789,000,000,000

Answer 1

first step: count the trailing zeros. That gives you

15789 * 10^9

But scientific notation requires you to express the product as a power of 10 and a number from 1-10.

15789 is 1.5789 * 10^4
because you have to shift the decimal point 4 places to the left. Now just add the exponents to get

1.5789 * 10^13

To do it all in one go, just count how many places you have to shift the decimal point to arrive at a number between 1 and 10 in front. In this case, if you shift the point 13 places to the left, you end up with 1.5789
