The property $\sqrt [ n ] { a \cdot b } = \sqrt [ n ] { a } \cdot \sqrt [ n ] { b }$ says that we can simplify radicals when the operation in the radicand is multiplication. Algebra 2 1) Simplify the radicals if necessary to get the same radicand 2) Add or subtract the like terms. Subtraction of radicals follows the same set of rules and approaches as addition: the radicands and the indices (plural of index) must be the same for two (or more) radicals to be subtracted. adding and subtracting 2 and 3 digit numbers worksheets ; prentice hall geometry book ch 7 ; free .
