Answer:
35√(x^2y)

Explanation:

To solve this exercise you must apply the proccedure shown below:

- Apply multiplication, as following:


4(5√(x^2y))+3(5√(x^2y))=20√(x^2y)+15√(x^2y)

- As you can see, the index of the radical in the first term is 2 and the index of the radical in the second term is also 2.

- You can observe that the radicands are the same.

- Therefoe, as the index of the first radical is equal to the index of the second radical and the radicands are the same, you can make the addition. Then, you obtain:


35√(x^2y)
