Answer:

Step-by-step explanation:
I'm gonna assume your assignment is to rewrite without negative exponents?

multiply the exponent into the parentheses, 
= 
now move the negative exponents "downstairs"
=
negative exponents in denominator move up, in numerator move down
simplifying now
= 
the other way to do this is to move the entire inside down, then multiplying the exponent, like this
=
then move things up and down
both ways will get you the same answer
