Solve exponential equations.
Solve logarithmic equations.
Equations with variables in the exponents, such as
are called exponential equations.
Sometimes, as is the case with the equation , we can write each side as a power of the same number:
We can then set the exponents equal and solve:
We use the following property to solve exponential equations.
This property follows from the fact that for any , , is a one-to-one function. If , then . Then since f is one-to-one, it follows that . Conversely, if , it follows ...
