com contas + resposta pf urgente :(


-4+5-(3+2)

-2²-5-(3+2)-1

(-5)²- [4-(3+7) ]

(7-4)²- [-2+4(2-3)]³

(-5+2)² - (4+3-9)³

(-4+1)°- [4 +7-9 (3-5) ]

[-7+2 (4-7)² ] -4-(8-7)²

(5 +2-3)² : 8 + (3²-2 x 3)

Answer 1

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

-2²-5-(3+2)-1=
-4-5-5-1= -15

(-5)²-[4-(3+7)]
 25-[4-10]
 25+6= 31

(7-4)²-[-2+4(2-3)]³
(3)²-[-2+4-1]³
  9-[+1]³=
  9-1=8

(-5+2)²-(4+3-9)³
(-3)²-(-2)³=
9+8=17

(-4+1)º-[4+7-9(3-5)]
 (-3)º-[4+7-9-2]
  1-0= 1

[-7+2(4-7)²]-4-(8-7)²
[-7+2(-3)²]-4-(1)²
[-7+2+9]-4-1
4-4-1= -1

(5+2-3)²:8+(3²-2x3)
(4)²:8+(9-6)
 16:8+3=
    2+3=5
