7.1 nth Roots and Rational Exponents Notes B Example 3: Approximating a Root with a Calculator Use a calculator to approximate

Rules for real nth roots: 1.If n is odd, then 2.If n is even and (a) a > 0, then (b) a = 0, then (c) a < 0, then

Example 4: Solving Equations Using nth Roots (a) 2x 4 = 162 (b) (x – 2) 3 = 10
