Hi there! The answer is n = 10.
![(2 {x}^{9} {y}^{n} )(4 {x}^{2} {y}^{10} ) = 8 {x}^{11} {y}^{20}](https://tex.z-dn.net/?f=%282%20%7Bx%7D%5E%7B9%7D%20%20%7By%7D%5E%7Bn%7D%20%29%284%20%7Bx%7D%5E%7B2%7D%20%20%7By%7D%5E%7B10%7D%20%29%20%3D%208%20%7Bx%7D%5E%7B11%7D%20%20%7By%7D%5E%7B20%7D%20)
As you see at the powers of x, we need to add the exponents of the power we when multiply them.
![{x}^{9} \times {x}^{2} = {x}^{9 + 2} = x {}^{11}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B9%7D%20%20%5Ctimes%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B9%20%2B%202%7D%20%20%3D%20x%20%7B%7D%5E%7B11%7D%20)
The powers of y work the same way.
![{y}^{n} \times {y}^{10} = {y}^{n + 10} = {y}^{20}](https://tex.z-dn.net/?f=%20%7By%7D%5E%7Bn%7D%20%20%5Ctimes%20%20%7By%7D%5E%7B10%7D%20%20%3D%20%20%7By%7D%5E%7Bn%20%2B%2010%7D%20%20%3D%20%20%7By%7D%5E%7B20%7D%20)
Hence, n = 10, since
