8x[5-(-2)]-48÷[6+(-14)]-11x(10(-7)]+36÷[(-1)-(-10]=
3(6-4)+2{2(2-4)+(5-3)-6(4-5)+(6+2)=​

Answer 1

Respuesta:

1)-40,5

2)700

3) 30

Explicación paso a paso:

1)(42+20)÷4-2x(9÷3)-2x[18+3x(13-9)-5]=

62÷4-2x3-2(18+3x4-5)

15,5-6-2(18+12-5)

15,5-6-2x25

15,5-6-50 = -40,5

2) 8x[5-(-2)]-48÷[6+(-14)]-11x(10(-7)]+36÷[(-1)-(-10]=

8x(-10)-48÷(6-14)-11x(-70)+36÷(-1+10)

-80-48÷(-8)+770+36÷9

-80+6+770+4= 700

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

​3x2+2(2x(-2)+2-6x(-1)+8

6+2(-4+2+6+8)

6+2x12

6+24 = 30
