1. 7.5 Warm-Up Solve. 1. x5/2 = 32 2. x2/3 + 15 = 24 x2/3 = 9

2. 7.5 Solving Radical Equations
Objective - 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

3. 7.5 Solving Radical Equations
Example 1: 3
Solve: x – 4 = 0
x = 4 3
( x) = 4 3
x = 64

4. Example 2: x = 25 Solve: 2x3/2 = 250 x3/2 = 125 (x3/2)2/3 = 1252/3

5. Example 3: 2 = x Solve: 3x + 2 – 2 x = 0 3x + 2 = 2 x

6. Example 4: x = 2 and x = 8 Solve: x – 4 = 2x (x – 4)2 = ( 2x )2
