Chapter 4 - Exponential and Logarithmic Functions - Exercise Set 4.2: 84

Answer

8

Work Step by Step

We know that the logarithmic function of base 10, or the common logarithmic function, can be written as $f(x)=log_{10}x$ or as $f(x)=logx$. Therefore, $log_{10}8=log_{10}10^{8}=8$, because $(10)^{8}=10^{8}$.
