Example 2: Solve the following exponential equation, round your answer to 3 decimal places. 2 −1=3+2 SOLUTION: -Since the bases cannot be related, we are going to use the power rule to pull the exponents down and solve for x. -Since the is no one logarithm that will undo both 2 and 3, we will simply use a natural logarithm in this case.

There are two strategies used for solving an exponential equation. The first strategy, if possible, is to write each side of the equation using the same base. Ex 1: Solve: 4 32xx 1 2 3 Both bases, 4 and 32, can be written as powers of base 2. (2 ) (2 )2 1 5 2 3xx Use the exponent rule for a power to a power (multiply exponents). 2 2 10 15 22xx
6.3 Solving Exponential Equations In Grade 9, Math 1201 and Math 2201, we looked at solving equations in which a variable was raised to an exponent. Example 1: Solve for : 2=64 Now, we will learn how to solve equations in which the variable is part of the exponent. Recall from Math 1201 we learned about prime factorization and exponents. For ...
