Answer: 6 X 10^-2
Step-by-step explanation: Move the decimal point (0.06) so that the dot is to the left of a non zero digit. (6.0). Put it times 10 and the exponent depends if you moved the decimal to the left (positive exponent) or to the right (negative exponent).
In this case we moved the decimal point 2 digits to the left where is where the -2 came from.
6 X 10^-2
