simplify the expression. write this answer in scientific notation.( 5 times 10 to a -5 power).(6 times 10 to a -2 power)
(5 X 10^-5) X (6 X 10^-2) Is this what you mean? If yes, then we have:
=3 X 10^-6
[5 * 10^-5] * [6 * 10^-2 ] =
[5 * 6] * [ 10^-5 * 10^-2] =
30 * [10^-7] move the decimal one place to the left and increase the power on 10 by 1
3.0 * 10^-6
