<u>Answer:</u>
![\frac{8\sqrt{y} }{x}](https://tex.z-dn.net/?f=%5Cfrac%7B8%5Csqrt%7By%7D%20%7D%7Bx%7D)
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
![\sqrt {\frac {128x^5y^6} {2x^7y^5} }](https://tex.z-dn.net/?f=%20%5Csqrt%20%7B%5Cfrac%20%7B128x%5E5y%5E6%7D%20%7B2x%5E7y%5E5%7D%20%7D%20)
To make it easier to solve, we can also write this expression as:
![\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}](https://tex.z-dn.net/?f=%20%5Csqrt%20%7B%5Cfrac%7B128%7D%7B2%7D%20%2A%20%5Cfrac%20%7Bx%5E5%7D%20%7Bx%5E7%7D%20%2A%20%5Cfrac%20%7By%5E6%7D%20%7By%5E5%7D%7D%20)
Now we will cancel out the like terms to get:
![\sqrt {64*\frac{1} {x^2}*y }](https://tex.z-dn.net/?f=%20%5Csqrt%20%7B64%2A%5Cfrac%7B1%7D%20%7Bx%5E2%7D%2Ay%20%7D%20)
Taking the square root of the terms to get:
![8*\frac {1}{x} .\sqrt{y}](https://tex.z-dn.net/?f=%208%2A%5Cfrac%20%7B1%7D%7Bx%7D%20.%5Csqrt%7By%7D%20)
![\frac{8\sqrt{y} }{x}](https://tex.z-dn.net/?f=%5Cfrac%7B8%5Csqrt%7By%7D%20%7D%7Bx%7D)
1=104 2=76 3=104 4=76 5=104 6=76 7=104 8=76
