Q2 of 28 Page 3

Construct a 2 × 2 matrix A = [ajj] whose elements ajj are given by :

Let A = [aij]2×2

So, the elements in a 2×2 matrix are


a11, a12, a21, a22,


A = …… (1)


a11 =


a12 =


a21 =


a22 =


So, from (1)


A =

If A is a square matrix such that A2 = A, then write the value of 7A – (I + A)3.

 3

If find the value of (x + y).

 4

If a matrix has 18 elements, what are the possible orders it can have? What, if it has 5 elements?

 5

If then compute 3A – 5B.
