A logarithm is the inverse of an exponent. The equation log x = 100 is another way of writing 10x = 100. This relationship makes it possible to remove logarithms from an equation by raising both sides to the same exponent as the base of the logarithm.

A logarithm is the opposite of a power. In other words, if we take a logarithm of a number, we undo an exponentiation. Let's start with simple example. If we take the base b=2 and raise it to the power of k=3, we have the expression 23.

Put in the base number e on both sides of the equation. e and ln cancel each other out leaving us with a quadratic equation.

If you have the same operation on both sides of an equation, they cancel each other out! Keep in mind that this only works when the logarithms on both sides of the equation have the same base. If you had a logarithm with base 3 on one side and a logarithm with base 7 on the other side, they won't cancel out.

The log base 3 and the base 3 of the exponential cancel each other out because they are inverses.
