To derive the antilog of a number in Excel, we use the following steps:

- We take the number whose antilog we want to find.
- We then take its logarithm using the
`LOG()`

function.
- We then use the
`EXP()`

function to calculate the antilog.

**Example:**

Find the antilog of 2.5 in Excel.

*Solution:*

**:**2.5

- The logarithm of 2.5 can be calculated using the
`LOG()`

- function as follows:

(0.405465108108164) ; LOG(2.5) = 0.405465108108164.

- Now that we have the logarithm of 2.5, we can calculate its antilog using the
`EXP()`

function as follows:

(1.97403068780791) ; EXP(0.405465108108164) = 1.97403068780791.

*Therefore, the antilog of 2.5 is 1.97403068780791.*
