Помогите,пожалуйста, вычислить. Подробно.

[latex] \dfrac{\log_714- \frac{1}{3}\log_756 }{\log_630-0.5\log_6150} = \dfrac{\log_714-\log_7 \sqrt[3]{56} }{\log_630-\log_6 \sqrt{150} } = \dfrac{\log_7 \frac{14}{ \sqrt[3]{56} } }{\log_6 \frac{30}{ \sqrt{150} } } =\\ \\ \\ = \dfrac{\log_7 \frac{14}{2 \sqrt[3]{7} } }{\log_6 \frac{30}{5 \sqrt{6} } } = \dfrac{\log_7(7^{1- \frac{1}{3} })}{\log_6(6^{1- \frac{1}{2} })} = \dfrac{1- \frac{1}{3} }{1- \frac{1}{2} } = \dfrac{6-2}{6-3} = \dfrac{4}{3} [/latex] [latex] \dfrac{3\log_72-0.5\log_764}{4\log_52+ \frac{1}{3}\log_527 } = \dfrac{\log_72^3-\log_764^{ \frac{1}{2} }}{\log_52^4+\log_5 \sqrt[3]{27} } = \dfrac{\log_78-\log_78}{\log_516+\log_53} =0[/latex]
