8.6 Solving Exponential and Logarithmic Equations

8.6 Solving Exponential and Logarithmic Equations

8.6 Solving Exponential and Logarithmic Equations. p. 501. Exponential Equations. One way to solve exponential equations is to use the property that if 2 powers w/ the same base are equal, then their exponents are equal. For b>0 & b ≠1 if b x = b y , then x=y.
