Hello, Flower9!
We have: \(\displaystyle \,(-6)^5(y^{-4})^5\)
and: \(\displaystyle \,(-6)(-6)(-6)(-6)(-6)\:=\: -7776\)
and: \(\displaystyle \,(y^{-4})^5 \;= \;y^{(-4)(5)} \;= \; y^{-20}\)
Hello, Flower9!
You lost your minus-signs . . .

Re: I think I have the answer...just need some guidance...ex
(y^(-4))^5 = y^(-20) = 1 / y^20
so: -7776 / y^20 : you were close enough...I guess! LEARN the rules :idea:
-6^5 = -7776Flower9 said:Simplify (-6y^-4)^5
I want to say the answer is 7776y^20
Thanks for any assistance!
