LOG is a function in Google Sheets that calculates the natural logarithm of a number. The function takes a single argument, the number to calculate the logarithm for. The LOG function can be used to calculate the logarithm of a number in any base, but it is most commonly used to calculate the logarithm of a number in base 10. The LOG function can be used in a number of different ways in Google Sheets. For example, the LOG function can be used to calculate the percentage change in a number over a given period of time. To do this, the LOG function is used to calculate the logarithm of the original number, and then the percentage change is calculated using the formula ((new_number - original_number) / original_number) * 100. The LOG function can also be used to calculate the compound annual growth rate (CAGR) of a number. To do this, the LOG function is used to calculate the logarithm of the original number, and then the CAGR is calculated using the formula (1 + LOG(1 + (original_number / 100))) ^ (1 / number_of_years).

The LOG function in Google Sheets returns the natural logarithm of a number. The syntax for the function is: LOG(number)

LOG(x) returns the natural logarithm of x. This function is especially useful when working with exponential data or formulas. For instance, the following formula calculates the percentage growth of a value over a period of time:

=LOG(A2/A1)^(1/T) - 1

Where A1 is the starting value, A2 is the ending value, and T is the number of time periods in between.
