Question

What is the value of x when the Richter scale rating is 4.4? Round your answer to the nearest hundredth. Pls help

Answer 1

Hello,

We have to use this relation : $\text{rating}=\log(\text{ratio})$

He we have :

$\log_{10}(x)=4.4\\\\\text{then }x=10^{\log_{10}(x)}\\\\\rightarrow x=10^{4.4}\\\\\rightarrow x=25\ 118.864\\\rightarrow x=25\ 118.86$
