Answer 2

`36{x}^(13) {y}^(7)`

EXPLANATION

The given expression is

`(4 {x}^(3) {y}^(5) )(3 {x}^(5) y)^(2)`

This is the same as:

`(4 {x}^(3) {y}^(5) )(3 {x}^(5) y)(3 {x}^(5) y)`

We multiply and also apply the law of exponents.

`{a}^(m) * {a}^(n) = {a}^(m + n)`

This will give us;

`4 * 3 * 3 * {x}^(3 + 5 + 5) {y}^(5 + 1 + 1)`

This simplifies to:

`36{x}^(13) {y}^(7)`
