For example
2.34 * 10^6 will be....
2,340,000
It is because if you have the positive powers, you move your decimal to the right. In this case the power is 6 so you move your decimal to the right 6 times.
Here's another example

Final tips: If you have positive power, move it to the right and if you have negative power, move it to the left.
