What is Log Base 3 of 66?

The below is the work with steps to find what is log base 3 of 66 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 = 66
b = 3

Solution:
y = log₃ 66
= log(3 x 2 x 11)
= log₃(3) + log₃(2) + log₃(11)
= 1 + 0.6309 + 2.1827
= 3.8136
log₃(66) = 3.8136
