Returns the the logarithm of a number given a base. Learn more
LOG is a function in Google Sheets that returns the logarithm of a given number to a specified base. If the base is not specified, the function returns the logarithm of the given number to the base 10.
The function takes one or two arguments:
value: the number whose logarithm you want to calculate. base (optional): the base of the logarithm. If this argument is not specified, the function assumes a base of 10. The syntax for using the LOG function in Google Sheets is:
=LOG(value, [base])
For example, if you want to find the logarithm base 2 of the number 8, you can use the LOG function in Google Sheets as follows:
=LOG(8, 2)
The result would be 3, which is the logarithm base 2 of 8.
If you want to find the logarithm to a different base, you can specify the base as the second argument. For example, if you want to find the logarithm base 5 of the number 125, you can use the LOG function in Google Sheets as follows:
=LOG(125, 5)
The result would be 3, which is the logarithm base 5 of 125.
