Now try Exercise 79(b). 22 Chapter P Prerequisites Radical expressions can be combined (added or subtracted) if they are like radicals—that is, if they have the same index and radicand. For instance, Ί2, 3Ί2, and 12Ί2 are like radicals, but Ί3 and Ί2 are unlike radicals. To determine whether two radicals can be combined, you should first simplify each radical.
