簡約 (3.4*10^{-2})(1.25)

解

簡約

(3.4 \cdot 1 0^{- 2}) (1.25)

0.0425

解答ステップ

(3.4 \cdot 1 0^{- 2}) (1.25)

規則を適用する:

(a) = a

(1.25) = 1.25

= 3.4 \cdot 1 0^{- 2} \cdot 1.25

数を乗じる:

3.4 \cdot 1.25 = 4.25

= 4.25 \cdot 1 0^{- 2}

= 1 0^{- 2} \cdot 4.25

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 4.25

1 0^{2} = 100

= \frac{1}{100} \cdot 4.25

\frac{1}{100} \cdot 4.25 = \frac{4.25}{100}

= \frac{4.25}{100}

数を割る:

\frac{4.25}{100} = 0.0425

= 0.0425
