化简 0.78-(0.05916)/4 log_{10}(1/((1/x)^2))

解答

化简

0.78 - \frac{0.05916}{4} lo g_{10} (\frac{1}{( \frac{1}{x} ) ^{2}})

\frac{39}{50} - \frac{1479 lo g _{10} ( x )}{50000}

求解步骤

0.78 - \frac{0.05916}{4} lo g_{10} (\frac{1}{( \frac{1}{x} ) ^{2}})

\frac{0.05916}{4} = \frac{5916}{400000}

= 0.78 - \frac{5916}{400000} lo g_{10} (\frac{1}{( \frac{1}{x} ) ^{2}})

化简

\frac{5916}{400000} lo g_{10} (\frac{1}{( \frac{1}{x} ) ^{2}}) : \frac{1479 lo g _{10} ( x )}{50000}

= 0.78 - \frac{1479 lo g _{10} ( x )}{50000}

0.78 = \frac{39}{50}

= \frac{39}{50} - \frac{1479 lo g _{10} ( x )}{50000}
