What is Log Base 2 of 28?

The below is the work with steps to find what is log base 2 of 28 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 = 28
b = 2

Solution:
y = log₂ 28
= log(2 x 2 x 7)
= log₂(2) + log₂(2) + log₂(7)
= 1 + 1 + 2.8074
= 4.8074
log₂(28) = 4.8074
