Question

simplify.
76.5*10^-3

Answer 1

We do the same as before :)
\[76.5\times10^{-3}\] = 0.0765

Answer 2

All it is doing is moving the decimal point. Since we are using the decimal system each spot is weighted. So when we have anything times a 10^n or 10^-n we are shifting the decimal point n times to the right or the left.
