What is Log Base 4 of 84?

The below is the work with steps to find what is log base 4 of 84 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 = 84
b = 4

Solution:
y = log₄ 84
= log(4 x 3 x 7)
= log₄(4) + log₄(3) + log₄(7)
= 1 + 0.7925 + 1.4037
= 3.1962
log₄(84) = 3.1962
