7.5 Warm-Up Solve. 1. x5/2 = 32 2. x2/3 + 15 = 24 x2/3 = 9
7.5 Solving Radical EquationsObjective - To be able to solve square root and other radical equations. Radical Equation: an equation that has a variable in a radicand or a fractional exponent
7.5 Solving Radical EquationsExample 1: 3 Solve: x – 4 = 0 x = 4 3 ( x) = 4 3 x = 64
Example 2: x = 25 Solve: 2x3/2 = 250 x3/2 = 125 (x3/2)2/3 = 1252/3
Example 3: 2 = x Solve: 3x + 2 – 2 x = 0 3x + 2 = 2 x
Example 4: x = 2 and x = 8 Solve: x – 4 = 2x (x – 4)2 = ( 2x )2
