Let a ,b ,c be positive and not all equal. Show that the value of the determinant |[a, b, c],[b, c, a],[ c, a ,b]| is negative.

Let a, b, c be positive and not all equal. Show that the value of the determinant |[a,b,c],[b,c,a],[c,a,b]| is negative

Let a, b, c be positive and not all equal. Show that the value of the determinant |[a,b,c],[b,c,a],[c,a,b]| is negative

If a, b, c are positive and unequal, show that value of the determinant Delta=|a b c b c a c a b| is negative.

If a, b, c are positive and unequal show that value of the determinant Delta=|[a, b, c],[ b, c, a],[ c, a, b]| is negative.

If a, b, c are positive and unequal, show that value of the determinant Delta=|(a,b,c),(b,c,a),(c,a,b)| is negative

If a,b,c are positive and unequal, show that value of the determinant Delta=|{:(a,b,c),(b,c,a),(c,a,b):}| is negative

If, a,b,c are positive and unequal,show that value of the determinant Delta ={:|( a,b,c),( b,c,a),( c,a,b)|:} is negative
