180\div 360× 4^2

解答

180 \div 360 \times 4^{2}

解答

8

求解步骤

180 \div 360 \times 4^{2}

遵循 PEMDAS 运算顺序

计算幂值

4^{2} : 16

4^{2}

4^{2} = 16

= 16

= 180 \div 360 \times 16

乘除（左右）

180 \div 360 \times 16 : 8

180 \div 360 \times 16

180 \div 360 = \frac{180}{360}

= \frac{180}{360} \times 16

\frac{180}{360} \times 16 = 8

\frac{180}{360} \cdot 16

对数字约分

\frac{180}{360} = \frac{1}{2}

= \frac{1}{2} \cdot 16

\frac{1}{2} \cdot 16 = 8

\frac{1}{2} \cdot 16

将项转换为分式:

16 = \frac{16}{1}

= \frac{1}{2} \cdot \frac{16}{1}

使用分式法则:

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

= \frac{1 \cdot 16}{2 \cdot 1}

\frac{1 \cdot 16}{2 \cdot 1} = 8

\frac{1 \cdot 16}{2 \cdot 1}

\frac{1 \cdot 16}{2 \cdot 1} = \frac{16}{2}

\frac{1 \cdot 16}{2 \cdot 1}

数字相乘:

1 \cdot 16 = 16

= \frac{16}{2 \cdot 1}

数字相乘:

2 \cdot 1 = 2

= \frac{16}{2}

= \frac{16}{2}

数字相除:

\frac{16}{2} = 8

= 8

= 8

= 8

= 8

= 8
