What is logarithm example?
logarithm, the exponent or the power for which you must base to give a particular number. Expressed mathematically, x is the logarithm of n with base b if bx = n, in which case we write x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 for base 2, or 3 = log2 8.
