Construct Formula Log For Free

Logarithms were invented in the 17th century as a calculation tool by Scottish mathematician John Napier (1550 to 1617), who coined the term from the Greek words for ratio (logos) and number (arithmos).

For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100. This is an example of a base-ten logarithm.log2 8 = 3. because. 23 = 8. In general, you write log followed by the base number as a subscript.log.log a = r.ln.ln a = r.

Log Transformation in Excel To apply a log transformation to a dataset in Excel, we can use the =LOG10() function.

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.
