Question

si a = 4; b = 5; c = 8; d = 10; e = -6, halla el valor de cada expresion a. (a x b) / d=
b. (b x c x e) / (a x b)=
c. [b (d + e)] x [e (c + d)]=
d. [(c + a ) (b + d] / [(a + b) d]
e. [( d + e) / a] x [e + (b + d)]=

Answer 1

A)
(4x5)/10 = 20/10 = 2

B)
(5x8x-6)/(4x5)= - 240/20= -12

C)
[5(10x-6)]x[-6(8x10)]
=[5(-60)]x[-6(80)]
=(-300)(-480)
=144000

D)
[(8+4)(5+10)/[(4+5)10]
= [(12)(15)]/[9(10)]
=180/90
=2

E)
[(10-6)/4]x[-6+(5+10)]
=[4/4]x[-6(15)]
=(1)(-90)
= -90
