What is Log Base 10 of 80?

The below is the work with steps to find what is log base 10 of 80 shows how the input values are being used in the log base 10 functions. Formula:
log_b(x) = y, if b^y = x

Input:
x = 80
b = 10

Solution:
y = log₁₀ 80
= log(10 x 2 x 2 x 2)
= log₁₀(10) + log₁₀(2) + log₁₀(2) + log₁₀(2)
= 1 + 0.301 + 0.301 + 0.301
= 1.903
log₁₀(80) = 1.903
