If $\log_{10}{2}=0.3010,then \log_{10}{80}$ is equal to :
1.6020
1.9030
3.9030
None of these
Explanation:
$\log_{10}{80}$=$\log_{10}{8 \times 10}$
=$\log_{10}{8}+\log_{10}{10}$
=$\log_{10}{2^{3}}+1$
=$3 \log_{10}{2}+1$
=$(3 \times 0.3010)+1$
=1.9030
$\log_{10}{80}$=$\log_{10}{8 \times 10}$
=$\log_{10}{8}+\log_{10}{10}$
=$\log_{10}{2^{3}}+1$
=$3 \log_{10}{2}+1$
=$(3 \times 0.3010)+1$
=1.9030
