# LOGARITHMIC AND EXPONENTIAL                                           EQUATIONS ## THERE ARE 3 MAIN TYPES OF EQUATIONS

1. =b

a. First you want to get the same base on both sides

ex. Solve . =7776               Get the same base on both sides = Put the exponents equal to each other

x=5

b. OR you can take the log of both sides

ex. Solve. =7776               Take the log of both sides

log =log7776      Move the exponents out in front of the log

xlog6=log7776       Divide to get the x by itself

x= x=5

2. a. To solve this type of equation go to exponential form ( )

ex. Solve.  Change the equation to exponential form. (  Take the cube root of both sides 3. a.To solve this type of equation you can remove the logs from each side of the equation. You can only do this if the logs have the same base.

So if the logs have the same base, then a=b.

ex. Solve. Since both the bases are the same put x equal to 10 Solve the following type of equations by using the best method:
