What is Log Base 2 of 68?

The below is the work with steps to find what is log base 2 of 68 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 = 68
b = 2

Solution:
y = log₂ 68
= log(2 x 2 x 17)
= log₂(2) + log₂(2) + log₂(17)
= 1 + 1 + 4.0875
= 6.0875
log₂(68) = 6.0875
