`|{:(1,a,bc),(1,b,ca),(1,c,ab):}|`

Evaluate Delta = {:[ (1,a,bc),( 1,b,ca),(1,c,ab)]:}

Evaluate Delta = {:[ (1,a,bc),( 1,b,ca),(1,c,ab)]:}

Find the minors and cofactos of each entry of the first column of the matrix A ad hence find the value of the determinant in each case: A = [(1,a,bc),(1,b,ca),(1,c,ab)]

Prove that abs{:(1, a, bc),(1, b , ca),(1, c, ab):}= abs{:(1, a,a^2),(1, b, b^2),(1, c, c^2):}

If Delta=|{:(1,bc,a),(1,ca,b),(1,ab,c):}| , then minor of element ab is :

|{:(1,1,1),(a,b,c),(bc,ca,ab):}|=(a-b)(b-c)(c-a)

Prove the following : |{:(1,1,1),(a,b,c),(bc,ca,ab):}|=(a-b)(b-c)(c-a)

Prove that {:[(1,ab,a+b),(1,bc,b+c),(1,ca,c+a):}]=(a-b)(b-c)(c-a)

|(1,1,1),(a,b,c),(bc,ca,ab)|=
