R0907 a.s. http://faculty.valenciacc.edu/ashaw/ INTERMEDIATE ALGEBRA GPS # 32 7.3 OPERATIONS ON RADICAL EXPRESSIONS I NAME: Useful Guidelines: If n a and n b are real numbers, and 0 b ! and n is a natural number, then * n n n a b ab ! = and n n n a a b b = . For example: 4 4 4 8 2 8 2 2 ! = ! = and 3 3 3 8 8 2 27 3 27 = = * NOTE: n n n a b a b + ! + and n n n a b a b ! " ! Only radical expression with the same index and the same radicand may be combined (combining the like terms or same family only).
