Question

How do you solve $log\left(x\right)=-0.123$?

Answer 1

Solve for $x$ using the given relation

$\log \left(x\right)=-0.123$

Since the base of the logarithm is not given, we can assume it to be $10$

$\Rightarrow$$\log x=-0.123={\log }_{10}x$

$\Rightarrow$ $x={10}^{-0.123}$ $....\left[\because {\log }_a\left(b\right)=x\Rightarrow b=a^x\right]$

$\Rightarrow$ $x=0.7534$

Hence, the value of $x$ is $0.7534$
