Because a number in scientific notation has to be in the form of:
x%2A10%5Ey where x%3C10 and x%3E0
We have to first make your number less than 10 and greater than 1.
That would be 7.9.
Now, how many places did you move the decimal point over from 7900000 to 7.9? I'll give you a hint. It's 6.
So in the above equation, y=6 and x=7.9.
7.9%2A10%5E6
And you're done. =)

You need one digit in front of the decimal x 10 to what ever numbered power that you need to move the decimal to get back to the original number.
790000=7.90000 x 10^5
If you have to move the decimal backwards to get back to the original number make the exponent negative:
.000079=7.9 x 10^-5
Hope that helps.
Happy Calculating!!!
