Question

Calcule o valor das expressões numéricas?
E a questão número 4 tá
Por favor e pra amanhã

Answer 1

a) 5-{+3-[(+2)²-(-5)²+6-4]}=
    5-{+3-[4-25+6-4]}=
    5-{+3-[-19]}=
    5-{+3+19}=
    5-22 = -17

b) 15-{-3+[(5-6)²*(9-8)²+1]}=
    15-{-3+[1²*1²+1]}=
    15-{-3+[1*1+1]}=
    15-{-3+[1+1]}=
    15-{-3+2}=
    15-{-1}=
    15+1=16

c) 18-{6-[-2-(-2)³-3-(3-2)³]+5}=
    18-{6-[-2-(-8)-3-(1)³]+5}=
    18-{6-[-2+8-3-1]+5}=
    18-{6-[2]+5}=
    18-{9}=9

d) -2+{-5-[-2-(-2)³-(3-2)³]+5}=
    -2+{-5-[-2-(-8)-(1)³]+5}=
    -2+{-5-[-2+8-1]+5}=
    -2+{-5-[5]+5}=
    -2+{-5}=-7

e) 4-{(-2²*(-3))-[-11+(-3)*(-4)]-(-1)}=
    4-{(-4*(-3))-[-11+12]+1}=
    4-{(12)-[-11+12]+1}=
    4-{(12)-1+1}=
    4-{12}=-8

Answer 2

a)(-3)^3-13=
-27-13=
-40

b)(-4)^2+(-2)^4
16+16
32

c)(-3)^2+(-2)^3
9 -8
1

d)(-1)^6+(-3)^3
1 -27
-26

e)(-2)^3+(-1)^5
-8-1
-9



4-a)5-{+3-[(+2)^2-(-5)^2+6-4]}
5-{+3-[+4-25+6-4]}
5-{+3-[-21+6-4]}
5-{+3-[-15-4]}
5-{+3-[-19]}
5-{+3+19}
5-22
-17

b)15-{-3+[(5-6)^2. (9-8)^2+1]}
15-{-3+[-1.+1+1]}
15-{-3+[-1+1]}
15-{-3+0}
15-{-3}
15+3
18

c)18-{6-[-2-(-2)^3-3-(3-2)^3]+5}
18-{6-[-2-(-8)-3-(1)^3]+5}
18-{6-[-2-(-8)-3-1]+5}
18 -{6-[-2+8-3-1]+5}
18-{6-[+6-3-1]+5}
18-{6-[+2]+5}
18-{6-2+5}
18-{9}
18-9
9

d)-2+{-5-[-2-(-2)^3-3-(3-2)^3]+5}
-2+{-5-[-2-(-8)-3-(+1)]+5}
-2+{-5-[-2+8-3-1]+5}
-2+{-5-[+2]+5}
-2+{-5-2+5}
-2+{-2}
-2-2
-4


e)4-{(-2^2. (-3)-[-11+(-3). (-4)]-(-1)}
4-{(-4.-3-[-11+(+12)]-(-1)}
4-{(-4.-3-[-11+12]-(-1)}
4-{(-4.-3-[+1]-(-1)}
4-{(-4.-3-1+1)}
4-{12-1+1}
4-{+12}
4-12
-8



me desculpe se houver algo errado
