WebTo simplify surds using addition and subtraction, first fully simplify each individual surd. Then only add and subtract surds that have the same number under the root. For example, 2√3 + 4√3 = 6√3. If the surds do not have the same number under the root, they cannot be added. Simply add or subtract the number in front of each surd. WebA surd is said to be in its simplest form when the number under the root sign has no square factors. For example 72 can be reduced to 4 × 18 = 2 18. But 18 still has the factor 9, so …
