Answer 1

8 goes in the first box

3 goes in the second box

The expression is
`(8)/(3)x^4y`

==================================================

Work Shown:

`z = 9xy * \left((2)/(3)x\right)^3\\\\z = 9xy * (2^3)/(3^3)x^3\\\\z = 9xy * (8)/(27)x^3\\\\z = 9*(8)/(27)*x*x^3*y\\\\z = (9*8)/(27)*x^4y\\\\z = (9*8)/(9*3)*x^4y\\\\z = (8)/(3)x^4y\\\\`
