Hello!</h2>
The answer is:
The solution of the problem is 328
<h2>Why?</h2>
First, we need to remember the following roots property:
![\sqrt[n]{a^{m} }=a^{ \frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D%3Da%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%7D)
Then, the expression:

Can be written as:
![(4x-16)^{\frac{1}{2}}=\sqrt[2]{4x-16}](https://tex.z-dn.net/?f=%284x-16%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Csqrt%5B2%5D%7B4x-16%7D)
Now, rewriting the equation, we have:
![\sqrt[2]{4x-16}=36](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B4x-16%7D%3D36)
Squaring both sides, and groping like terms, we have:
![(\sqrt[2]{4x-16})^{2} =36^{2}\\\\4x-16=1296\\4x=1296+16\\4x=1312\\x=\frac{1312}{4}=328](https://tex.z-dn.net/?f=%28%5Csqrt%5B2%5D%7B4x-16%7D%29%5E%7B2%7D%20%3D36%5E%7B2%7D%5C%5C%5C%5C4x-16%3D1296%5C%5C4x%3D1296%2B16%5C%5C4x%3D1312%5C%5Cx%3D%5Cfrac%7B1312%7D%7B4%7D%3D328)
Hence,

The solution of the problem is 328
Have a nice day!
