Work Step by Step
An exponential equation is an equation containing a variable in an exponent.
Some exponential equations can be solved by expressing each side of the equation as a power of the same base.
All exponential functions are one-to-one. Thus, no two different ordered pairs have the same second component. Therefore, if $b$ is a positive number other than $1$ and $b^M=b^N,$ then $M=N$.
