LOG10 Examples Basic usage: To calculate the base-10 logarithm of the number 100, you would use the formula =LOG10(100). This would return the value 2, as 10^2 = 100. Using cell references: If you have a number in cell A1, you can calculate its base-10 logarithm by using the formula =LOG10(A1).

Display formulas using the Show Formulas command To show formulas in Excel, you can click on the Formulas tab and then click Show Formulas. This will show all formulas in the Excel worksheet.

To calculate the value of log 10 using the natural log function, follow these steps: Recall that log 10 is the power to which 10 must be raised to produce 10. This means log 10 = 1. where ln is the natural logarithm and e is the base of the natural logarithm.

To convert from Log10 to natural logs, you multiply by 2.303. Analogously, to convert in the other direction, you divide by 2.303. Taking the antilog of a number undoes the operation of taking the log. Therefore, since Log10(1000) = 3, the antilog10 of 3 is 103 = 1,000.

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. In the same fashion, since 102 = 100, then 2 = log10 100.

The value of log 10 is 1. Log 10 can also be represented with base e (natural logarithm) as ln(10) ? 2.302585. The logarithm of a number tells us the power to which the base must be raised to produce that number.

The syntax for the LOG function is =LOG(number, base), where number is the value for which you want to find the logarithm, and base is the desired base. You can use the EXP function to reverse the LN function.

Excel LOG Function Summary. The Excel LOG function returns the logarithm of a given number, using a supplied base. The base argument defaults to 10 if not supplied. Get the logarithm of a number. The logarithm. =LOG (number, base) number - Number for which you want the logarithm. base - optional Base of the logarithm.
