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.

No. For example, the square roots of prime numbers cannot be simplified.

The square roots of 13 cannot be simplified.

No. A number will have a rational square root, only if both the numerator and denominator of the simplified fraction are squares of integers.

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.

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.)

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.

That's the same as the square root of 3, multiplied by i.

It can add, subtract, multiply, divide and do 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.

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

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.

If it asks for the opposites, then add a negative.
