What is Log Base 2 of 38?

The below is the work with steps to find what is log base 2 of 38 shows how the input values are being used in the log base 2 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 38
b = 2

Solution:
y = log₂ 38
= log(2 x 19)
= log₂(2) + log₂(19)
= 1 + 4.2479
= 5.2479
log₂(38) = 5.2479
