- How do you solve equations when the variable is in the exponent?
- How can you use logarithms and the change of base formula to solve equations?
- How do you solve 4^x = 8 by making the bases the same?
- How do you solve 4^x = 80 using logarithms and the change of base formula?
- How do you solve 5^2x = 35?
- How do you solve e^x = 20?
- How do you solve 10^(2x - 3) = 48?
- How can you check your solution to equations where the variable is in the exponent?
This lesson uses the change of base formula that was discussed in the previous lesson to solve equations where the variable is in the exponent. All steps are shown and explained in this video. The process for solving is moving the variable exponent down to the front of the expression by taking the log of both sides, and then solving by getting the variable by itself. This process is very important for future math problems you will encounter.
