Given A = and A t is its transpose matrix. Find : (i) 2A + 3A t (ii) 2A t - 3A (iii) (iv)

. (i) Substituting value of A and A t in 2A + 3A t we get, Hence, 2A + 3A t = (ii) Substituting value of A and A t in 2A t - 3A we get, Hence, (iii) Substituting value of A and A t in we get, Hence, (iv) Substituting value of A and A t in we get, Hence,
