Question

Arithmetic opeations on two different square roots

Answer 1

Operations with Square Roots

You can perform a number of different operations with square roots. Some of these operations involve a single radical sign, while others can involve many radical signs. The rules governing these operations should be carefully reviewed.

Under a single radical sign

You may perform operations under a single radical sign.

Example 1

Perform the operation indicated.











When radical values are alike

You can add or subtract square roots themselves only if the values under the radical sign are equal. Then simply add or subtract the coefficients (numbers in front of the radical sign) and keep the original number in the radical sign.
