• You already read that logs and exponentials are inverses.

• You can use them to undo one another.

• When solving for a variable, it is often helpful to rewrite the question in the opposite form.

• Please note: the answer to a log equation is the exponent.

Did you get 3?

Notice 5*5*5 = 53 = 125 so our answer would again be 3.

In conclusion, since b is equal to this many a’s being multiplied,

then if you raise c by 1…you’ll have to multiply one more a times b.

Remember,
