化简 (4+((2-5)^2-4(7-5)^3+2(15/3)))-sqrt(16)

解答

化简

(4 + ((2 - 5)^{2} - 4 (7 - 5)^{3} + 2 (\frac{15}{3}))) - 16

- 13

求解步骤

(4 + ((2 - 5)^{2} - 4 (7 - 5)^{3} + 2 (\frac{15}{3}))) - 16

(4 + ((2 - 5)^{2} - 4 (7 - 5)^{3} + 2 (\frac{15}{3}))) - 16 = 4 + (2 - 5)^{2} - 4 (7 - 5)^{3} + 2 (\frac{15}{3}) - 16

= 4 + (2 - 5)^{2} - 4 (7 - 5)^{3} + 2 \cdot \frac{15}{3} - 16

(2 - 5)^{2} = 9

4 (7 - 5)^{3} = 32

2 \cdot \frac{15}{3} = 10

16 = 4

= 4 + 9 - 32 + 10 - 4

数字相加:

4 + 9 - 32 + 10 - 4 = - 13

= - 13
