Answer:


7√(6)

Explanation:

You can only add radicals if the value inside the square root symbol is the exact same, therefore, this one is 6. To find the sum, we can add the values outside the square root symbol (3 and 4) to get our new radical.

We can also check this.


3√(6) = √(9*6) = √(54) ≈ 7.35


4√(6) = √(16*6) = √(96) ≈ 9.8


7√(6) = √(49*6) = √(294) ≈ 17.15

7.35+9.8 = 17.15

Hope this helped!
