What is Log Base 3 of 42?

The below is the work with steps to find what is log base 3 of 42 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 = 42
b = 3

Solution:
y = log₃ 42
= log(3 x 2 x 7)
= log₃(3) + log₃(2) + log₃(7)
= 1 + 0.6309 + 1.7712
= 3.4021
log₃(42) = 3.4021
