SOLVING EXPONENTIAL EQUATIONS


An exponential equation is one where the variable is in the exponent.
Here are some common types. Click on each to see how to solve it.



2x = 64
Trial & Error



5x = 25
Equate the Bases

8x - 3 = (2(x - 2))2
Equating Bases II



When you can't easily equate the bases ...



4x = 85
Use logs [1]



2(x - 5) = 3(x - 8)
Use logs [2]



162 · 252x = 17x
Use logs [3]
