Solving Exponential and Logarithmic Equations
General steps in solving Exponential and logarithmic equations...
1) get the exponential or logarithmic term by itself on one side of the =.
2) to get the variable out of the exponent or logarithm, apply the inverse function to both sides of the equation.
These are general steps, depending on the problem, there can be quicker and easier ways to solve.
