Question

Simplify. Remember to write the powers as a positive number. a^−2*b^5

Answer 1

remember that
`a^(-b)=(1)/(a^b)`

so

`a^(-2)b^5=`

`((1)/(a^2))(b^5)=`

`(b^5)/(a^2)`

Answer 2

b^5 divided by a^2

I don't know how to do the fraction thingy on this thing but to explain it, since a has a negative exponent it has to move to the denominator for this equation to work. That is why the b^2 is on top and the a^2 on the bottone. Once the a^-2 goes to the bottom, it loses the negative sign.
