Question

How do you evaluate ${\log }_{8}1$?

Answer 1

Calculate the value of ${\log }_{8}1$

Let ${\log }_{8}1=x$

Using the definition of $\log$ rewrite the given expression

$$\begin{gathered} \Rightarrow 8^x=1 \\ \Rightarrow 8^x=8^0 \end{gathered}$$

Compare L.H.S and R.H.S

$\Rightarrow x=0$

Hence the value of ${\log }_{8}1$ is $0$
