## narissa one year ago what is the value of the expression 1/5^-5

1. whovianchick

3125, since a negative exponent is in the denominator, you have to make it positive and move it to the numerator, or 1*5^5/1= 5^5 = 3125

2. narissa

im not sure if that's right

3. whovianchick

Why not?

4. whovianchick

$1\div5^5$

5. whovianchick

wait I typed that last one wrong, imagine the little five is negative

6. whovianchick

You move it to the numerator, and make it positive so it's $1\times5^5$

7. whovianchick

5^5= 3125
