What is Log Base 2 of 30?

The below is the work with steps to find what is log base 2 of 30 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 = 30
b = 2

Solution:
y = log₂ 30
= log(2 x 3 x 5)
= log₂(2) + log₂(3) + log₂(5)
= 1 + 1.585 + 2.3219
= 4.9069
log₂(30) = 4.9069
