To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above: 7√(3.2x)-3√(3.16x)-3√(3.8x)
2. To simplify it, you can factor √x, as following:
√x(7√(3.2)-3√(3.16)-3√(3.8))
3. When you solve the values inside the parenthesis, you obtain:
1.34√x
Therefore, the answer is: 1.34√x
