6(1/2)((-1)^2(2))

解答

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

解答

6

求解步骤

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

遵循 PEMDAS 运算顺序

计算括号内的值

((- 1)^{2} (2)) : 2

(- 1)^{2} (2)

计算幂值

(- 1)^{2} : 1

(- 1)^{2}

使用指数法则:

(- a)^{n} = a^{n},

若

n

是偶数

(- 1)^{2} = 1^{2} = 1

= 1

= 1 \cdot (2)

乘除（左右）

1 \cdot (2) : 2

1 \cdot (2)

使用法则:

(a) = a

(2) = 2

= 1 \cdot 2

数字相乘:

1 \cdot 2 = 2

= 2

= 2

= 6 (\frac{1}{2}) \cdot 2

乘除（左右）

6 (\frac{1}{2}) \cdot 2 : 6

6 (\frac{1}{2}) \cdot 2

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

6 (\frac{1}{2})

使用法则:

(a) = a

(\frac{1}{2}) = \frac{1}{2}

= 6 \cdot \frac{1}{2}

6 \cdot \frac{1}{2} = 3

6 \cdot \frac{1}{2}

将项转换为分式:

6 = \frac{6}{1}

= \frac{6}{1} \cdot \frac{1}{2}

使用分式法则:

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

= \frac{6 \cdot 1}{1 \cdot 2}

\frac{6 \cdot 1}{1 \cdot 2} = 3

\frac{6 \cdot 1}{1 \cdot 2}

\frac{6 \cdot 1}{1 \cdot 2} = \frac{6}{2}

\frac{6 \cdot 1}{1 \cdot 2}

数字相乘:

6 \cdot 1 = 6

= \frac{6}{1 \cdot 2}

数字相乘:

1 \cdot 2 = 2

= \frac{6}{2}

= \frac{6}{2}

数字相除:

\frac{6}{2} = 3

= 3

= 3

= 3

= 3 \cdot 2

3 \cdot 2 = 6

= 6

= 6
