Homework Help: Simple Clarification needed

Moninder · Sep 8, 2012

I need to write this in scientific notation:

(6.67x10^-11)(5.97x10^24)
________________________
( 6.38x10^6)^2

Is
6.24x10^17 right?

I did the following:
First took all the numbers, with the x10^# and solved it to 6.24
Now I did the same to the x10^# and got 10^17

Did you square 6.38×10⁶ in the denominator?

It looks as if you didn't.
