Question

Gente Por favor ajude eu com essa contas e precisso de ajuda
com cálculo e a resposta!!!

Answer 1

1)a)14:7+3=2+3=5

b)10:5-(1+3)=2-1-3=-2

c)6-8:2+3=6-4+3=5

d)(2-4):(7-9)+1=-2:(-2)+1=1+1=2

e) (3x2):2+10=6:2+10=3+10=13

f) (1-7):(9-12)+1=-6:(-3)+1=2+1=3

g) -10+8:4-7x1=-10+2-7=-15

h) -14:2+(1-3)=-7-2=-9

i)8-8:4+2x3=8-2+6=12

J)-1-[8-(4:2)-1]=-1-[8-2-1]=-1-8+2+1=-6

k)16:2+1-4-3=8+1-4-3=2

l)-18:2+(4x2)-3=-18:2+8-3=-9+8-3=-4

m)-8+3x2-[5-3-(8:2)]=-8+6-[5-3-(8:2)]=-8+6-[5-3-4]=-8+6-5+3+4=0

n) )7-[6-10:5+4-(3+1)]=7-[6-2+4-(3+1)]=7-[6-2+4-3-1]=7-6+2-4+3+1=3

o)-20+5:5+1+17+3x2=-20+5:5+1+17+6=-20+1+1+17+6=5

p)13-(1-3)+6:2-1:1+6=13-(1-3)+3-1+6=13-1+3+3-1+6=23

q)-[2-(5:5-7)+9-1]-8=-[2-(1-7)+9-1]-8=-[2-1+7+9-1]-8=-2+1-7-9+1-8=-24

r) -9-[6-3x2-8:4-(1+1)]=-9-[6-6-8:4-(1+1)]=-9-[6-6-2-(1+1)]=-9-[6-6-2-1-1]=-9-6+6+2+1+1=-5

continuação

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

b)-8+4:2-6+10x1-(-1)^2= -8+4:2-6+10-1=-8+2-6+10-1=-3

c)8-[5-(8-9)^2-4+3x1]+5=8-[5-(-1)^2-4+3]+5=8-[5-1-4+3]+5=8-5+1+4-3+5=10

d)(-6):2+5x1-(-2)^2+3^2=(-6):2+5-(-2)^2+3^2=-3+5-4+9=7

e)[(7-6)^2x(8-7)^3]x(10-12)^2-1=[(1)^2x(1)^3]x(-2)^2-1=[1x1]x4-1=1x4-1=4-1=3

f)[(-1)^3x(-2)^2+3]^2-3x2+5=[(-1)x(4)+3]^2-3x2+5= [-4+3]^2-6+5=[-1]^2-6+5=1-6+5=0

g)10-{-3+[(4-5)^2-(8-7)^2+1]}=10-{-3+[(-1)^2-(-1)^2+1]}=10-{-3+[1-1+1]}=10-{-3+1-1+1}=

=10+3-1+1-1=12                                                                                                                            

h)-14+(-1)^3x(-1)^2-2x5+20=-14+(-1)^3x(-1)^2-10+20=-14-1x1-10+20=-14-1-10+20=-5

i)-20-[40-(10+50)-10]:10=-20-[40-60-10]:10=-20-30:10=-20-3=-23

j)raiz de 36:(-1)^2+raiz de 25-raiz de 16+3=raiz de 36:1+ raiz de 25-raiz de 16+3=

=6:1+5-4+3=6+5-4+3=10
