Question

Need a little help with the math questions I displayed

Answer 1

`Use:\\(a^n)/(a^m)=a^(n-m)\\\\(a^n)^m=a^(n\cdot m)\\\\(a\cdot b)^n=a^n\cdot b^n`


`\left((xy^2)/(x^(-3)y^3)\right)^(-4)=\left(x^(1-(-3))y^(2-3)\right)^(-4)=\left(x^4y^(-1)\right)^(-4)\\\\x^(4\cdot(-4))y^(-1\cdot(-4))=\boxed{x^(-16)y^4}=\boxed{(y^4)/(x^(16))}`

Answer 2

( xy^2/ x^-3y^3)^-4
