What is Log Base 4 of 28?

The below is the work with steps to find what is log base 4 of 28 shows how the input values are being used in the log base 4 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 28
b = 4

Solution:
y = log₄ 28
= log(4 x 7)
= log₄(4) + log₄(7)
= 1 + 1.4037
= 2.4037
log₄(28) = 2.4037
