解答ステップ

- \frac{15}{2} (\frac{1}{10 0 ^{2}}) + \frac{15}{2}

規則を適用する:

(a) = a

(\frac{1}{10 0 ^{2}}) = \frac{1}{10 0 ^{2}}

= - \frac{15}{2} \cdot \frac{1}{10 0 ^{2}} + \frac{15}{2}

- \frac{15}{2} \cdot \frac{1}{10 0 ^{2}} = - \frac{3}{4000}

= - \frac{3}{4000} + \frac{15}{2}

- \frac{3}{4000} + \frac{15}{2} = \frac{29997}{4000}

= \frac{29997}{4000}
