Convert 91007500 to scientific notation

Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.

91007500

We move the decimal place first so that the number is within our range:

9.1007500

Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7

Therefore in scientific notation it is 9.1007500 x 10^7

Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:

9.1 x 10^7
