" If "|[a,b,0],[0,a,b],[b,0,a]|=0,

If Delta=|(-a,2b,0),(0,-a,2b),(2b,0,-a)|=0 then

Prove that: |[0,a,-b],[-a,0,-c],[ b, c,0]|=0 .

The value of the determinant |{:(a, b,0), (0,a, b),(b,0,a):}| is equal to

The value of the determinant |{:(a, b,0), (0,a, b),(b,0,a):}| is equal to- a. a^3-b^3 b. a^3+b^3 c. 0 d. none of these

The value of the determinant |{:(a, b,0), (0,a, b),(b,0,a):}| is equal to- a. a^3-b^3 b. a^3+b^3 c. 0 d. none of these

If a, b, c are non-zero real numbers, then the inverse of the matrix A [[a,0,0],[0,b,0],[0,0,c]] is

If B=[[0,5,7],[0,0,6],[0,0,0]] , show that B^4=O

If A=[[1,0,0],[0,1,0],[a,b,-1]] and A=A^(-1) then a+b=?

If A=[(b,0,0),(0,b,0),(0,0,b)] then the value of |A||adjA| is
