4.52× 10^{-1}6/0.5× 25

解答

4.52 \times 1 0^{- 1} 6/0.5 \times 25

135.6

求解步骤

4.52 \times 1 0^{- 1} 6/0.5 \times 25

数字相除:

6 \div 0.5 = 12

= 4.52 \times 1 0^{- 1} \times 12 \times 25

使用指数法则:

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

1 0^{- 1} = \frac{1}{10}

= 12 \times 25 \times 4.52 \times \frac{1}{10}

分式相乘:

a \times \frac{b}{c} = \frac{a \times b}{c}

= 4.52 \times \frac{1 \times 12 \times 25}{10}

\frac{1 \times 12 \times 25}{10} = 30

= 30 \times 4.52

数字相乘:

4.52 \times 30 = 135.6

= 135.6
