Question

If A is a matrix of order (a+2) X 3 and B of order (b-2) X c and AB is of order 4 X 2, find a+b+c​

Answer 1

Answer:

Order of AB =2×3.3×5⇒2×5

(AB) t =5×2.

Answer 2

Answer:

Order of AB =2×3.3×5⇒2×5

Order of AB =2×3.3×5⇒2×5(AB)

Order of AB =2×3.3×5⇒2×5(AB) T

Order of AB =2×3.3×5⇒2×5(AB) T =5×2.
