WebA logarithm is the inverse of the exponential function. Specifically, a logarithm is the power to which a number (the base) must be raised to produce a given number. For example, \log_2 64 = 6, log2 64 = 6, because 2^6 = 64. 26 = 64. In general, we have the following definition: z z is the base- x x logarithm of y y if and only if x^z = y xz = y. WebOct 24, 2024 · Logarithm Notation. To make it easier to solve for the exponents, logarithms use a special kind of notation. The expression x y = z in exponent form would turn into log x (z) = y in logarithm ...
