Answer 2

Answer:

4*10^-5

Step-by-step 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.
