Answer 1

a) (3-5-4)/4
-6/4=-3/2
b)(-6/5)(-5/2)(-1/3)=-(6×5×1)/(5×2×3)=-1
c)(-14+15-1)/6=0/6=0
d)1/2 × 1/2 × (-1/8) = -1/32
e)(2/3)^-3
(3/2)^3= 27/8
f) (4×10)^-2
40^-2
1/40^2 = 1/1600

Answer 2

Efectue las operaciones indicadas y simplifique si es posible el resultado
a. 3/4-5/4-4/4= (3-5-4)/4= -6/4= - (6:2)/(4:2)= -3/2= -1 1/2;

b.(-6/5)(-5/2)(-1/3)= (-6• -5• -1)/(5•2•3)= -30/30= -(30:30)/(30:30)= -1/1= -1;

c.-7/3+5/2-1/6= -(7•2)/(3•2)+ (5•3)/(2•3) -1/6= -14/6+ 15/6- 1/6= 15/6 -14/6 - (1/6)=0;

d.(1/2dividido por 2) dividido(-1/8)= (1/2 :2): (-1/8)= 1/2• 1/2• (-8/1)= -8/4= -(8:4)/(4:4)= -2/1= -2;

e.(2/3)elevado a menos 3= (2/3) ^-3= (3/2)^ 3= (3)^3/ (2)^3= (3•3•3)/(2•2•2)= 27/8= 3 3/8;

f. 4 x 10 elevado a menos 2= (4) • (10)^-2= (4)• (1/10)^2= (4)• (1)^2/(10)^2= (4)• (1•1)/(10•10)= 4• 1/100=4/100= 0,04.
