解答ステップ

1.0034 ln (\frac{523}{303}) - 0.287 ln (\frac{800}{95})

対数の規則を適用する:

a lo g_{c} (b) = lo g_{c} (b^{a})

1.0034 ln (\frac{523}{303}) = ln ((\frac{523}{303})^{1.0034})

= ln ((\frac{523}{303})^{1.0034}) - 0.287 ln (\frac{800}{95})

対数の規則を適用する:

a lo g_{c} (b) = lo g_{c} (b^{a})

0.287 ln (\frac{800}{95}) = ln ((\frac{800}{95})^{0.287})

= ln ((\frac{523}{303})^{1.0034}) - ln ((\frac{800}{95})^{0.287})

対数の規則を適用する:

lo g_{c} (a) - lo g_{c} (b) = lo g_{c} (\frac{a}{b})

ln ((\frac{523}{303})^{1.0034}) - ln ((\frac{800}{95})^{0.287}) = ln (\frac{( \frac{523}{303} ) ^{1.0034}}{( \frac{800}{95} ) ^{0.287}})

= ln (\frac{( \frac{523}{303} ) ^{1.0034}}{( \frac{800}{95} ) ^{0.287}})

\frac{( \frac{523}{303} ) ^{1.0034}}{( \frac{800}{95} ) ^{0.287}} = 0.93817 \dots

= ln (0.93817 \dots)
