簡約 (7.72*10^{-2})(3.17)

解

簡約

(7.72 \cdot 1 0^{- 2}) (3.17)

0.244724

解答ステップ

(7.72 \cdot 1 0^{- 2}) (3.17)

規則を適用する:

(a) = a

(3.17) = 3.17

= 7.72 \cdot 1 0^{- 2} \cdot 3.17

数を乗じる:

7.72 \cdot 3.17 = 24.4724

= 24.4724 \cdot 1 0^{- 2}

= 1 0^{- 2} \cdot 24.4724

指数の規則を適用する:

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

1 0^{- 2} = \frac{1}{1 0 ^{2}}

= \frac{1}{1 0 ^{2}} \cdot 24.4724

1 0^{2} = 100

= \frac{1}{100} \cdot 24.4724

\frac{1}{100} \cdot 24.4724 = \frac{24.4724}{100}

= \frac{24.4724}{100}

数を割る:

\frac{24.4724}{100} = 0.244724

= 0.244724
