Simplify. ( w^2/-3u^4)^2. Write your answer without parentheses.

w^4 / (9u^8)

Step-by-step explanation:

( w^2/-3u^4)^2

We know that ( a/b) ^c = a^c  / b^c

( w^2) ^2/ (-3u^4)^2

We know that a^b^c = a^(b*c)  

w^(2*2)/ (-3u^4)^2

We know ( ab) ^c = a^c * b^c

w^4/ (( -3)^2 u^4^2)

w^4/(9 u^(4*2))

w^4 / (9u^8)
