化简 10+(10-(12)/(2^2)3)7

解答

化简

10 + (10 - \frac{12}{2 ^{2}} \cdot 3) \cdot 7

解答

17

求解步骤

10 + (10 - \frac{12}{2 ^{2}} \cdot 3) \cdot 7

(10 - \frac{12}{2 ^{2}} \cdot 3) \cdot 7 = 7

(10 - \frac{12}{2 ^{2}} \cdot 3) \cdot 7

10 - \frac{12}{2 ^{2}} \cdot 3 = 1

10 - \frac{12}{2 ^{2}} \cdot 3

\frac{12}{2 ^{2}} \cdot 3 = 9

\frac{12}{2 ^{2}} \cdot 3

消掉

\frac{12}{2 ^{2}} : 3

\frac{12}{2 ^{2}}

因式分解

12 : 2^{2} \cdot 3

12

因式分解数字:

12 = 4 \cdot 3

= 4 \cdot 3

因式分解数字:

4 = 2^{2}

= 2^{2} \cdot 3

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

约分:

2^{2}

= 3

= 3 \cdot 3

数字相乘:

3 \cdot 3 = 9

= 9

= 10 - 9

数字相减:

10 - 9 = 1

= 1

= 1 \cdot 7

数字相乘:

1 \cdot 7 = 7

= 7

= 10 + 7

数字相加:

10 + 7 = 17

= 17
