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)

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.

Can every square root be simplified?
No. For example, the square roots of prime numbers cannot be simplified.
How do you simplify square root of 13?
The square roots of 13 cannot be simplified.
Are all square roots rational?
No. A number will have a rational square root, only if both the numerator and denominator of the simplified fraction are squares of integers.
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.
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.)
Can every square root be simplified?
No. For example, the square roots of prime numbers cannot be simplified.
How do you simplify square root of 13?
The square roots of 13 cannot be simplified.
What is the square root of 126 in simplified mode?
The simplified radical expression of 126 is 3 roots of 14. 126 can be divided by the perfect square nine, fourteen times. As a result you have 3 roots of 14.
What is the square root of negative 3 simplified?
That's the same as the square root of 3, multiplied by i.
Are all square roots rational?
No. A number will have a rational square root, only if both the numerator and denominator of the simplified fraction are squares of integers.

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

Arithmetic with square roots?
You can combine square roots when you multiply or divide. For example: root(2) x root(3) = root(6). You cannot do the same for addition and subtraction. For example, root(2) + root(3) can't be simplified.
How do you know if a square root is simplifed?
A square root is simplified when: -The radicand has no perfect square factors other than 1 -The radicand has no fractions -There are no square roots in the denominator *Radicand: the number and/or variables underneath the square root sign
Can 3 divided by the square root of 2 be simplified?
In a way. You can multiply top and bottom by the square root of 2. This will not exactly make the expression simpler, but you'll get rid of the square root in the denominator (and transfer it to the numerator); this is considered to be the standard form for expressions which involve square roots. In other words, there should be no square roots in the denominator.
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.
