If m & n are positive AND m = n, then Can solve exponential equation by taking logarithm of each side of equation Only works with base 10
Solve each equation. Round to the nearest ten- thousandth.
Use to evaluate logarithm with any base For an and y positive numbers M, b, & c, with and
Use the change of base formula to evaluate and then convert to the different base log.
Can use change of base formula Take logarithm of each side using the base of exponent as base for logarithm Use change of base formula
Use change of base formula to solve.
Can solve exponential equations by graphing Use calculator and 2 equations (one for each side of =) Find intersection
Solve by graphing
