Divide the following: (5.6x10 to the -7 power meters) / (2.8x10 to the -10 power seconds)?

Question

The first measurement is in meters and the second measurements is in seconds.

Answer 1

division of powers
take the oposite of the bottom and add to the top so you have
(5.6*10^3meters)/ 2.8seconds
then you have
(2*10^3meters)/1 second

Answer 2

(5.6 * 10^-7)/(2.8 * 10^(-10))

(5.6/2.8) * 10^(-7 - (-10))

2 * 10^3 m/s
