Answer:

4*10^-5

Explanation:

  • Start by counting the zeros to the right of the decimal if 0<x<1. Stop when you hit a digit between 1 and 9
  • Add 1 to the number of zeros
  • This is the power
  • Express the number as one between 1 and 9
  • The power is changed to a negative, if 0<x<1

0.00004 has 4 zeros. Add 1 = 5

The power on 10 becomes negative (-5)

4 is a number between 1 and 9 inclusive.

4 * 10^-5
