What is Log Base 2 of 256?

The below is the work with steps to find what is log base 2 of 256 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 = 256
b = 2

Solution:
y = log₂ 256
= log₂ 2⁸
= 8 log₂ 2 = 8 x 1
log₂ 256 = 8
log₂(256) = 8
