Simplifying - Solution and Explanation

===================================

Hello! So...

We are given the following to simplify:

`7√(28x^6) -5√(63x^6)`

_________________________________________________

To solve this, we must simply simplify.

`7√(28x^6) =14√(7) x^3`

`5√(63x^6)=15√(7)x^3`

`=14√(7)x^3-15√(7)x^3`

Now, add the similar elements:

`14√(7)x^3 -15√(7) x^3=-√(7)x^3 \\`

Now, considering we are assuming all variables are positive in this situation, we need to convert the negative into a positive solution.

`=-√(7)x^3`

`= x^3√(7)`

^Hence, our solution.^
