What is Log Base 3 of 45?

The below is the work with steps to find what is log base 3 of 45 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 = 45
b = 3

Solution:
y = log₃ 45
= log(3 x 3 x 5)
= log₃(3) + log₃(3) + log₃(5)
= 1 + 1 + 1.465
= 3.465
log₃(45) = 3.465
