1

求解步骤

[(2^{3})^{- 2}]^{0.5} [(0.5)^{0.75}]^{- 4}

(2^{3})^{- 2} : 2^{- 6}

= (2^{- 6})^{0.5} [0. 5^{0.75}]^{- 4}

[0. 5^{0.75}]^{- 4} : 0. 5^{- 3}

= (2^{- 6})^{0.5} \cdot 0. 5^{- 3}

(2^{- 6})^{\frac{1}{2}} = \frac{1}{2 ^{3}}

= 0. 5^{- 3} \cdot \frac{1}{2 ^{3}}

使用指数法则:

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

0. 5^{- 3} = \frac{1}{0. 5 ^{3}}

= \frac{1}{2 ^{3}} \cdot \frac{1}{0. 5 ^{3}}

分式相乘:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 1}{2 ^{3} \cdot 0. 5 ^{3}}

数字相乘:

1 \cdot 1 = 1

= \frac{1}{2 ^{3} \cdot 0. 5 ^{3}}

2^{3} \cdot 0. 5^{3} = 1

= \frac{1}{1}

使用法则

\frac{a}{1} = a

= 1
