求解步骤

\frac{1}{256} \div 2^{8}

遵循 PEMDAS 运算顺序

计算幂值

2^{8} : 256

2^{8}

2^{8} = 256

= 256

= \frac{1}{256} \div 256

乘除（左右）

\frac{1}{256} \div 256 : \frac{1}{65536}

\frac{1}{256} \div 256

将项转换为分式:

256 = \frac{256}{1}

= \frac{1}{256} \div \frac{256}{1}

使用分式法则:

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

= \frac{1}{256} \cdot \frac{1}{256}

分式相乘:

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

= \frac{1 \cdot 1}{256 \cdot 256}

数字相乘:

1 \cdot 1 = 1

= \frac{1}{256 \cdot 256}

数字相乘:

256 \cdot 256 = 65536

= \frac{1}{65536}

= \frac{1}{65536}
