Answer 1


`9x^(4)` for
`(3x)^2`·
`x^(2)` and
`(x^(4))`·
`(y^(4))` for
`x^4`·
`(y^2)^3`·
`y^(-2)`

Explanation:

`(3x)^(2) (x^(2) )` Multiply in

`(9x^(2))(x^(2))` Multiply together

`9x^(4)`

`(x^(4))(y^(2))^(3) (y^(-2))`

`(x^(4))(y^(6))((1)/(y^(2)))` Multiply in

`(x^(4))((y^(6))/(y^(2)))` Multiply together

`(x^(4))(y^(4))`
