(2)^2(1/2)(1/3)

解答

(2)^{2} (\frac{1}{2}) (\frac{1}{3})

解答

\frac{2}{3}

+1

十进制

0.66666 \dots

求解步骤

(2)^{2} (\frac{1}{2}) (\frac{1}{3})

遵循 PEMDAS 运算顺序

计算幂值

(2)^{2} : 4

(2)^{2}

(2)^{2} = 4

= 4

= 4 (\frac{1}{2}) (\frac{1}{3})

乘除（左右）

4 (\frac{1}{2}) (\frac{1}{3}) : \frac{2}{3}

4 (\frac{1}{2}) (\frac{1}{3})

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

4 (\frac{1}{2})

使用法则:

(a) = a

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

= 4 \cdot \frac{1}{2}

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

4 \cdot \frac{1}{2}

将项转换为分式:

4 = \frac{4}{1}

= \frac{4}{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{4 \cdot 1}{1 \cdot 2}

\frac{4 \cdot 1}{1 \cdot 2} = 2

\frac{4 \cdot 1}{1 \cdot 2}

\frac{4 \cdot 1}{1 \cdot 2} = \frac{4}{2}

\frac{4 \cdot 1}{1 \cdot 2}

数字相乘:

4 \cdot 1 = 4

= \frac{4}{1 \cdot 2}

数字相乘:

1 \cdot 2 = 2

= \frac{4}{2}

= \frac{4}{2}

数字相除:

\frac{4}{2} = 2

= 2

= 2

= 2

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

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

2 (\frac{1}{3})

使用法则:

(a) = a

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

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

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

2 \cdot \frac{1}{3}

将项转换为分式:

2 = \frac{2}{1}

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

使用分式法则:

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

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

数字相乘:

2 \cdot 1 = 2

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

数字相乘:

1 \cdot 3 = 3

= \frac{2}{3}

= \frac{2}{3}

= \frac{2}{3}

= \frac{2}{3}

(+ 12) - (5 + 8)

(10-3)^2+2*[6-5(3^2-2)^2]

(10 - 3)^{2} + 2 \cdot [6 - 5 (3^{2} - 2)^{2}]

- 13 + 6 + (- 8) + 13

- 2 \times 0 + 2

(3)^{2} - 6 (3) + 10
