解答ステップ

39.9 \cdot 101.5 3^{- 0.995}

指数の規則を適用する:

a^{- b} = \frac{1}{a ^{b}}

101.5 3^{- 0.995} = \frac{1}{101.5 3 ^{0.995}}

= 39.9 \cdot \frac{1}{101.5 3 ^{0.995}}

39.9 \cdot \frac{1}{101.5 3 ^{0.995}} = \frac{39.9}{101.5 3 ^{0.995}}

= \frac{39.9}{101.5 3 ^{0.995}}

\frac{39.9}{101.5 3 ^{0.995}} = \frac{399}{10 \cdot 101.5 3 ^{0.995}}

= \frac{399}{10 \cdot 101.5 3 ^{0.995}}
