If P ` = [{:(3, 0), (0, lambda):}]` is scalar matrix then `lambda` = ____.

If A=[{:(6,0),(p,q):}] is a scalar matrix then the value of p and q are

Assertion (A) : If the matrix A=[{:(1,3,lambda+2),(2,4,8),(3,5,10):}] is singular , then lambda=4 . Reason (R ) : If A is a singular matrix, then |A|=0

If A = [{:(lambda,1),(-1,-lambda):}] , then for what values of lambda, A^(2) =0 ? …………..

If the rank of the matrix [(lambda,-1,0),(0, lambda,-1),(-1,0,lambda)] is 2, then find lambda .

If the matrix [[0,1,-2],[-1,0,3],[lambda,-3,0]] is singular,then lambda=

lambda ^ (3) -6 lambda ^ (2) -15 lambda-8 = 0

A= [{:(0,3),(2,0):}] and A^(-1)=lambda (adj, A) then lambda is equal to

A= [{:(0,3),(2,0):}] and A^(-1)=lambda (adj, A) then lambda is equal to
