4. Value of k, for which `A = [[k,8],[4,2k]]` is a singular matrix is:
a)`4` b) `-4`
c) `+-4` d) `0`

For what value of k ,the matrix [[2-k,3],[-5,1]] is singular.

If A=[[k,10],[3,5]] is a singular matrix,then the value of k is equal to

If A=[[2-k,2],[1,3-k]] is a singular matrix,then find the value of 5k-k^(2) .

If "A= [[k,10],[3,5]]" is a singular matrix,then the value of "k" is equal to: "

If A=[(1,k,3),(3,k,-2),(2,3,-4)] is singular then K=?

[" (A) "4],[" 2.If "A=[[k,10],[3,5]]" is a singular matrix,then the value of "k" is equal to : "],[[" (A) "0," (B) "6," (C) "-6," (D1/ "]]

If B=[{:(6,3),(-2,k):}] is singular matrix then the value of k is____

The value of k for which the points A(0, 1), B(2, k) and C(4,-5) are colinear is:

The value(s) of k for which the quadratic equation 2x^2 + kx + 2 = 0 has equal roots, is (a) 4 (b) pm 4 (c) -4 (d) 0
