Question

Assume that Y,W,P are matrices of order 3×k ,n×3 and p×k respectively. Find the restrictions on n,p,k so that PY +WY is defined.

Answer 1

Answer:

k = 3 ; p = n

Step-by-step explanation:

For two matrices A, B, of orders a x b, c x d, A + B is defined only if a = c and b = d [Orders of both matrices should be same];  AB is defined only if b = c [Order of AB becomes a x d]

For PY to be defined, k = 3 [Order of PY becomes p x k = p x 3]

For WY to be defined, 3 = 3 [Already correct][Order of WY becomes n x k = n x 3]

For PY + WY to be defined, p = n

Basically p and n can be anything as long as they are equal [Obviously they can only be natural numbers; otherwise the order of matrix would not be defined]
