Calculating Gravitational Force with Scientific Notation

In summary, to write (6.67x10^-11)(5.97x10^24)/(6.38x10^6)^2 in scientific notation, we first solve the numbers with the x10^# to get 6.24 as the numerator and 10^17 as the denominator. However, we need to square 6.38x10^6 in the denominator, which gives us 9.78x10^0 as the answer.

I need to write this in scientific notation:

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

Is
6.24x10^17 right?

Not correct.

Please, explain your workings.

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

I figured out the exponents to be x10^1
But can't get the number right

Did you square 6.38×106 in the denominator?

It looks as if you didn't.

Ok thank you, I figured it out 9.78x10^0 which is the answer
