RADICALS AND RATIONAL EXPONENTS WORKSHEET #2
REVIEW: nth Root: If , then b is the root of a. This is written. n is called the index of the radical. a is called the radicand. Roots as Rational Exponents: The root,, can be written as an exponent . - Notice the placement of the m and n. The root index is the denominator and the exponent is the numerator.
