    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

    Re: Simpe Clarification needed

    Did you square 6.38×106 in the denominator?

    It looks as if you didn't.
