• math -

If a number has a negative exponent, move the decimal to the left to convert
to Standard form. If the exponent is positive, move the decimal to the right.

1. 8.0*10^8 = 800,000,000 m/s.
We moved the decimal 8 places to the right.

2. 2.*10^-10 = 0.0000000002 nm.
We moved the decimal 10 places to the left.
