Answer 1

Respuesta:

f) -2.(8-11)+4+(-6)= -2.-3+4-6=6+4-6=4

g)-2+(-8+5).(-1-1)-4+(-6)= -2+(-3).(-2)-4-6= -2+6-10= -12+6= -6

h)(-5).(-3-5)+(-6).[3-(-3)]= (-5).(-8)+(-6).(3+3)= 40+(-36)= 40-36= 4

i) – [ – 3 – ( – 2 ) . 5 – ( – 4 ) . ( – 1 ) ] =  - [ -3-(-10)-4]=-[-3+10-4]=10-7=3

j) – 4 . [ – ( – 2 + 6 ) . ( – 5 ) – ( – 4 ) ] = -4.[-(4).(-5)(4)]= -4 [-4.-20]= -4.80= -320

k) – [ 3 . ( – 2 ) + ( – 4 ) . ( –2– 1 ) ] = - [-6+(-4).(-3)]= -(-6+12)=-(6)=-6

l) 4 – ( – 3 ) . ( – 2 ) – [ – ( – 3 ) – 8 ]  – 2 = (4+3).(-2)-(3-8)=7.(-2)-(-5)=7.(-2+5)=7.3=21
