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.
