Q15 of 307 Page 6

If S = [s_ij] is a scalar matrix such that s_ij = k and A is a square matrix of the same order, then AS = SA = ?

As, = k

Let {Square Matrix}

Hence, AS = SA = kA

Option (C) is the answer.

If and (A + B)² = A² + B², then values of a and b are

If is such that A² = I, then

If A is a square matrix such that A² = A, then (I + A)³ – 7A is equal to

If a matrix A is both symmetric and skew-symmetric, then

If S = [sij] is a scalar matrix such that sij = k and A is a square matrix of the same order, then AS = SA = ?
