What is Log Base 4 of 56?

The below is the work with steps to find what is log base 4 of 56 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 = 56
b = 4

Solution:
y = log₄ 56
= log(4 x 2 x 7)
= log₄(4) + log₄(2) + log₄(7)
= 1 + 0.5 + 1.4037
= 2.9037
log₄(56) = 2.9037
