Question

Hi can anybody tell me the answer

Answer 1

`\huge \purple { \boxed{ 8 {x}^(5) {y}^(7) }}`

Explanation:

`4 {x}^(2) {y}^(3) * 2 {x}^(3) {y}^(4) \\ = 2 * 4 * {x}^(2) * {x}^(3) * {y}^(3) * {y}^(4) \\ = 8 * {x}^(2 + 3) * {y}^(3 + 4) \\ \huge \red { \boxed{= 8 {x}^(5) {y}^(7) }}`

Answer 2

8x^5y^7

Step by step explanation

`4 {x}^(2) {y}^(3) * 2 {x}^(3) {y}^(4) \\ 4 * 2 * {x}^(2) * {x}^(3) * {y}^(3) * y ^(4) \\ 8 * {x}^(2 + 3) * {y}^(3 + 4) \\ =8 {x}^(5) {y}^(7)`
