# Rational Exponents and Radical Equations

A.10 nth Roots and Rational Exponents if n ≥ 3 and n is odd if n ≥ 2 and n is even

If n ≥ 2 and m ≥ 2 and the radicals are defined , then Simplify a radical :
Remove any perfect roots from the radicand.
No fractions under the radicand.
No radicals in the denominator .

Simplify : pA87 #18:      Radical Equations : put radical on one side and then undo by exponent.  Rational Exponents : Use rules of exponents to solve.
