And we get 9x is equal to negative five. Lets say we have the exponential equation two to the 3x plus five power is equal to 64 to the x minus seventh power. Therefore we have to factor 125 and write it as 5 elevated to 3.
If not go to Step 2.
Set up the equation so that you are taking the log of both sides. Use the theorem above that we just proved. Using Logs for Terms without the Same Base 1. Solving Exponential Equations with Different Bases Step 1.
