Question

How do you add `\sqrt { 52} + \sqrt { 13}`?

Answer 1

See below

Explanation:

We have to factor the numbers under the square root.

`52=2^2*13`

So `sqrt52` becomes `sqrt(2^2*13)=2sqrt13`

Since the numbers inside the square roots are the same, we can add them together.

`2sqrt13+sqrt13=3sqrt13`
