Logarithms are the inverse of exponents. A logarithm (or log) is the mathematical expression used to answer the question: How many times must one ?base? number be multiplied by itself to get some other particular number? For instance, how many times must a base of 10 be multiplied by itself to get 1,000?

The names of these rules are: Product rule. Division rule. Power rule/Exponential Rule. Change of base rule. Base switch rule. Derivative of log. Integral of log.

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
