|[a,a+b,a+2b],[a+2b,a,a+b],[a+b,a+2b,a]|=mb^(n)(a+b)," then "

a a+b a+2b 10. Using properties of determinants, show that |[a,a+b,a+2b],[a+2b,a,a+b],[a+b,a+2b,a]|=9b^2(a+b)

The value of Delta = |(a,a +b,a +2b),(a +2b,a,a +b),(a +b,a +2b,a)| is equal to

Using properties of determinant show that : |(a,a+b,a+2b),(a+2b,a,a+b),(a+b,a+2b,a)|=9b^2(a+b)

Using properties of determinats show that |{:(a,a+b,a+2b),(a+2b,a,a+b),(a+b,a+2b,a):}|=9b^2(a+b)

Without expanding the determinants,show that |(a,a+b,a+2b),(a+2b,a,a+b),(a+b,a+2b,a)|=9(a+b)b^2

Without expanding, prove the following |(a,a+b,a+2b),(a+2b,a,a+b),(a+b,a+2b,a)|=9(a+b)b^2

Prove: |(a, a+b, a+2b),( a+2b, a ,a+b ),(a+b, a+2b, a)|=9(a+b)b^2

Prove: |(a, a+b, a+2b),( a+2b, a ,a+b ),(a+b, a+2b, a)|=9(a+b)b^2

Prove that |[a+b,a+2b,a+3b] , [a+3b,a+4b,a+5b] , [a+5b,a+6b,a+7b]|=0

The determinant Delta=|(a,a+b,a+2b),(a+2b,a,a+b),(a+b,a+2b,a)|=
