What is Log Base 9 of 54?

The below is the work with steps to find what is log base 9 of 54 shows how the input values are being used in the log base 9 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 54
b = 9

Solution:
y = log₉ 54
= log(9 x 2 x 3)
= log₉(9) + log₉(2) + log₉(3)
= 1 + 0.3155 + 0.5
= 1.8155
log₉(54) = 1.8155
