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.)

How do you add simplified square roots?
You can add simplified square roots only if the radicals are the same and, in that case, you treat the radicals as you would treat a variable in algebra.For example, sqrt(18) + sqrt(50)= sqrt(9*2) + sqrt(25*2)= 3*sqrt(2) + 5*sqrt(2)= [3 + 5]*sqrt(2)= 8*sqrt(2)
How is combining like terms similar to adding and subtracting square roots?
In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.
Every positive number has 2 square roots a square root and its opposite?
Yes, but it is not the case that one is the square root and the other is its opposite. Both are equal square roots with the other one being its opposite.
What are all the square roots of 1600?
Like every other number 1600 has only two square roots, plus and minus 40.

What does the stepped reckoner do?
It can add, subtract, multiply, divide and do square roots.

Yes, but it is not the case that one is the square root and the other is its opposite. Both are equal square roots with the other one being its opposite.
2 and -2 are square roots of 4Then why -2 is not used in graph of square root function?
If it asks for the opposites, then add a negative.

How many square roots does 7 have?
Every number has two square roots. They're the same size, but one is positive and the other is negative.

How to get rid of sqare roots in an equation?
square the other side.
What other types of numbers are irrational?
square roots, pi
Which two numbers have square roots equal to themselves?
The square root of zero is zero and the square root of one is one. No other real numbers have square roots equal to themselves. In other words, the solution set to x=x2 is {0,1}
When you subtract one square number from the other and the answer is 9 what are the two square roots?
The roots are 4 and 5. If you subtract the square number 16 (4X4) from the square number 25 (5X5), you would get 9.
