Question

X : -7/11,Y:4/5,Z:3/8.verify that ( x×y)×z=x×(y×z).

Answer 1

Step-by-step explanation:

now, let the equesion....

• (X×Y)× Z = X×(Y×Z)

now, putting the all given valuer after simplifying.

then,

(-28/55)* 0.375 = (12/40)*(-0.636)

(-10.5/55) = (-7.62/40)

now, - sign are in both side, will be cancel out.

after simplifying,

0.190 = 0.190

so,

LHS= RHS

Therefore, the equation is Symmetric.
