You multiply the coefficients, and add the explonents

anonymous · Answer

so I multiply (8x10) and (7x10) and then when I get done with that ad the7 and 4?

anonymous · Answer

anonymous · Answer

I think it's the website going crazy.

anonymous · Answer

Did you get 56x10^11?

anonymous · Answer

I don't know  but yeah I was about to type that

anonymous · Answer

Now you just make it a scientific notation by moving the decimal point, but note that you also have to increase/decrease the exponent depends on where you move it.

anonymous · Answer

560x10^10 = 56x10^11 = 5.6x10^12 = 0.56x10^13
