What is Log Base 2 of 8192?

The below is the work with steps to find what is log base 2 of 8192 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 = 8192
b = 2

Solution:
y = log₂ 8192
= log₂ 2¹³
= 13 log₂ 2 = 13 x 1
log₂ 8192 = 13
log₂(8192) = 13
