<h3>Simplifying an expression</h3>
From the question, we are to simplify the give expression
The given expression is
![y^{3}\sqrt[5]{32x^{4} } - 7\sqrt[5]{x^{4}y^{15} }](https://tex.z-dn.net/?f=y%5E%7B3%7D%5Csqrt%5B5%5D%7B32x%5E%7B4%7D%20%7D%20%20-%207%5Csqrt%5B5%5D%7Bx%5E%7B4%7Dy%5E%7B15%7D%20%20%7D)






11. 
Multiply both sides by 2


Multiply both sides by a power of 3/2







x = 4
Hence,
