## How do you use LOG10 in Excel?

Log10 is used in Excel to change the base of a number from 10 to any other number. This is useful when working with large numbers or when you need to use a specific base for calculations. To use Log10 in Excel, type the number you want to change the base of into a cell, type "=LOG10(" and then drag the cell corner to include the full number. After the parentheses, type the number you want the base to be, for example, "=LOG10(A1)" would change the base of the number in A1 from 10 to 2. You can also use Log10 to change the base of a number that is already in a formula.

## What is the syntax of LOG10 in Excel?

The syntax for LOG10 in Excel is "=LOG10(number)". This function takes a number as an input and calculates the base 10 logarithm of that number.

## What is an example of how to use LOG10 in Excel?

LOG10 is a function in Excel that calculates the logarithm of a number to the base 10. The function takes in an input of a number and outputs the logarithm of that number. To use the function, you must first enter the function into the cell where you want the calculation to appear. Next, you must enter the number that you want to calculate the logarithm of. After you have entered both of those things, hit the enter button on your keyboard and the logarithm will appear in the cell. An example of how to use the LOG10 function in Excel is below.

In cell A1, I have entered the function =LOG10(A2). This function calculates the logarithm of the number in cell A2 to the base 10. In cell A2, I have entered the number 5. After hitting the enter button on my keyboard, the logarithm of 5 appears in cell A1, which is 0.69897.
