Question

Выполните действия:
1) 4 (-13-27)-2800: (-10)²-25 (-1);
2) (25-(25-(25-(25-15))))-(-4)²+43•(-1);
3) (16-(16-(16-18))) (36-(36-(36-24)));
4) (-2-4-6-(-1-3-5)) (1600-2600):(-10)².

Answer 1

Ответ:

1) -13-27=-40

-40*4=-160

2800:(-10)²=2800:100=28

25*(-1)=-25

-160-28=-188

-188-(-25)=-188+25=-163

3) (16-(16-(16-18)))=16-16+16-18=-2

(36-(36-(36-24)))=36-36+36-24=12

-2*12=-24

2) (25-(25-(25-(25-15))))=25-25+25-25+15=15

15-(-4)²=15-16=-1

43*(-1)=-43

-1+(-43)=-1-43=-44

4) (-2-4-6-(-1-3-5))=-2-4-6+1+3+5=-3

-3*(1600-2600)=-3*(-1000)=3000

3000:(-10)²=3000:100=30
