what expression do i use to find the diffrence between 5.0 x 10^-4m and 3.0 x 10^-5

Answer 1

To find the difference between 5.0 x 10^-4m and 3.0 x 10^-5m, you would subtract the second value from the first value.

(5.0 x 10^-4m) - (3.0 x 10^-5m) = (5.0 - 0.3) x 10^-4m = 4.7 x 10^-4m.

Therefore, the difference between the two values is 4.7 x 10^-4m.
