To describe: The general method for solving exponential and logarithmic equations with different bases.
Answer to Problem 73E
Both types of equations can be solved graphically with ease, but algebraically the solution will be a little bit tedious.
Explanation of Solution
Given information: Exponential and logarithmic equations are with different bases.
Calculation: Suppose the given equations are in the general form that is
Take logarithm both sides to solve,
Logarithmic equations having different bases,
By using change-of-base property,
This equation is tedious to solve unless
Mostly, the graphical intersection of equations gives the solution, and it is easy too.
