What is Log Base 2 of 4096?

The below is the work with steps to find what is log base 2 of 4096 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 = 4096
b = 2

Solution:
y = log₂ 4096
= log₂ 2¹²
= 12 log₂ 2 = 12 x 1
log₂ 4096 = 12
log₂(4096) = 12
