Calculating Gravitational Force with Scientific Notation

[Moninder]

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

 

[Moninder]

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
