Hi,

Answer: D) 100,000

My work: This can easily be solved by taking this and turning it into a fraction which I will show in my numerical work. This can easily solved in a 4 step method!

My Numerical work:

1. 10^-2=

1(10^2 x 10^3)

Simplify:

2. 10^5

Simplify/ Which equals:

3.10x10x10x10x10=

4. 100,000

I Hope this Helps!

Note that if there is a negative in the power sign, flip the placement of the number

10^-2 = 1/(10^2)

1(/10^2 x 10^3) = 1/10^5

(1/10^5)^-1 = 10^5

10^5 = 10 x 10 x 10 x 10 x 10 = 100,000

D) 100,000 is your answer

hope this helps
