When we have two terms that contain the same type of root the radical in both terms is a square root the radical in both terms is a cube root etc and identical radicands the expressions under the radical signs in the two terms are the same they are like terms and adding and subtracting is really simple The key to combining square roots by addition or subtraction is look at the radicand If these are the same then addition and subtraction are possible If not then we cannot combine the two radicals Example Simplify displaystyle 3 sqrt 11 7 sqrt 11 3 11 7 11 The two square roots have the same radicand displaystyle sqrt 11 11
