To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
x√(4x)
2. You must simplify it as below:
(x)(4x)^1/2
3. By the exponents properties, you have:
4x^3/2
√(4x^3)
4. Finally, you obtain:
2√(x^3)
5. Therefore, as you can see, the answer is: 2√(x^3)
