LOG: The LOG function allows you to calculate logarithms with any base. The syntax is =LOG(number, [base]), where number is the positive numeric value and base is the base of the logarithm. If the base is omitted, it defaults to base 10. LN: The LN function calculates the natural logarithm (base e) of a given number.

f(x) = loga x The base of the logarithm is a. This can be read it as log base a of x. The most 2 common bases used in logarithmic functions are base 10 and base e.

Mathematically, Logarithms are expressed as, m is the Logarithm of n to the base b if bm = n, which can also be written as m = logb n. For example, 43 = 64; hence 3 is the Logarithm of 64 to base 4, or 3 = log464. Similarly, we know 103 = 1000, then 3 = log101000.
