Question

For the following values of x, y and z, find the products (X*y)*z and X*(y*z) and observe the result (X*y)*z=X*(y*z).​

Answer 1

Answer:

(i) [4x35]=[y1z5]

As the given matrices are equal, their corresponding elements are also equal.

Comparing the corresponding elements, we get: x=1,y=4, and z=3

(ii) [x+y5+z2xy]=[6528]
