What is Log Base 5 of 45?

The below is the work with steps to find what is log base 5 of 45 shows how the input values are being used in the log base 5 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 45
b = 5

Solution:
y = log₅ 45
= log(5 x 3 x 3)
= log₅(5) + log₅(3) + log₅(3)
= 1 + 0.6826 + 0.6826
= 2.3652
log₅(45) = 2.3652
