It depends on which square roots. I think some examples will help. I will write S(2) to mean the square root of 2 for this answer. So S(2)+S(2)=2S(2). There is no other way to combine them. However, S(8)+S(2)=S(4x2)+S(2)=2S(2)+S(2)=3S(2) So you can combine. Basically, you combine like terms and whenever possible try to create like terms. If you had S(21)+S(19), they are NOT like terms and there is nothing more you can combine. You are done.

Why does every positive numbers have 2 square roots?
Because multiplying negative numbers together gives a positive answer. So the square root of nine is both three and minus three.
How do you add simplified square roots?
To add simplified square roots, first simplify each individual square root expression. Then, if the numbers inside the square roots are the same, add or subtract the numbers outside the square roots. Finally, combine the numbers inside the square roots if possible. For example, to add √8 and √18, simplify them individually as 2√2 and 3√2. Since the numbers inside the square roots are the same, add 2 and 3 to get 5√2 as the final result.

How do you add square roots to other square roots?
Other than by calculating the square roots and adding the results there is no general method. However, by factorising the number (of which the square root is being taken), the square root can be simplified which may let the square root be added. Examples: √2 + √8 = √2 + √(4×2) = √2 + √4 × √2 = √2 + 2√2 (1 + 2)√2 = 3√2 √12 + √27 = √(4×3) + √(9×3) = 2√3 + 3√3 = 5√3 (Remember that the radical sign (√) means the positive square root.)
