Question

for the following values of X Y and Z find the product of (X into Y) in to Z and X into (Y into Z) and observed that the result (X into Y) in into Z is equal to x into (y into Z )​. x=-3,y=-4/9,z=-7/3 ​

Answer 1

Answer:

Mark as brainliest

Step-by-step explanation:

given: x=3,y=4/9,x=7/3

solve: i) (X x Y)xZ = (3x4/9)7/3 = 4/3x7/3 = 28/9

         ii) Xx(YxZ) = 3x(4/9x7/3) = 3x28/27 = 28/9

i = ii

28/9 = 28/9

hence proved

Answer 2

Step-by-step explanation:

Given that,

x=-3

y=-4/9

z=-7/3

Equation 1st - (xy)z

= {(-3)*(-4/9)}*(-7/3) = -28/9

Equation 2nd - (yz)x

= {(-4/9)*(-7/3)}*(-3) = -28/9

Equation 1 = Equation 2

Hence prooved.
