# What is Log Base 3 of 18?

## How to Find log_{3}(18)? - Work with Steps

The below is the work with steps to find what is log base 3 of 18 shows how the input values are being used in the log base 3 functions.
__Formula:__

log_{b}(x) = y, if b^{y} = x

__Input:__

`x` = 18

`b` = 3

__Solution:__

y = log_{3} 18

= log(3 x 3 x 2)

= log_{3}(3) + log_{3}(3) + log_{3}(2)

= 1 + 1 + 0.6309

= 2.6309

log_{3}(18) = 2.6309
