1. Taking the n th Root to Solve Equations Chapter 7.1

2. Recall: Solving Quadratic Equations by Taking the Square Root of Each Side Examples: Solve each equation. 1.x 2 = 49 2.(x – 1) 2 = 64 3.3x 2 = 27

3. Taking the n th Root of each side 1.Isolate the variable or expression being raised to a power 2.The exponent is n, take the n th root of both sides of the equation (use a calculator). 3.If n is even, remember your variable could be positive or negative (you need ± sign). 4.If an expression was being raised to a power, continue to isolate variable.
