If a, b, c are even natural numbers, then `Delta=|{:(a-1,a,a+1),(b-1,b,b+1),(c-1,c,c+1):}|` is a multiple of

If a,b,c are even natural numbers, then |{:(a-1,a,a+1),(b-1,b,b+1),(c-1,c,c+1):}| is equal to

If a,b,c are non zero real numbers then Delta=|(1,ab,1/a+1/b),(1,bc,1/b+1/c),(1,ca,1/c+1/a)| equals

The value of Delta = |(1,a,b +c),(1,b,c +a),(1,c,a +b)| , is

The value of Delta = |(1,a,b +c),(1,b,c +a),(1,c,a +b)| , is

If a, b and c are all different from zero and Delta = |(1 +a,1,1),(1,1 +b,1),(1,1,1 +c)| = 0 , then the value of (1)/(a) + (1)/(b) + (1)/(c) is

If a, b and c are all different from zero and Delta = |(1 +a,1,1),(1,1 +b,1),(1,1,1 +c)| = 0 , then the value of (1)/(a) + (1)/(b) + (1)/(c) is

The value of |{:(1,1,1),(b+c,c+a,a+b),(b+c-a,c+a-b,a+b-c):}| is

If a_(1),b_(1),c_(1),a_(2),b_(2),c_(2) "and" a_(3),b_(3),c_(3) are three digit even natural numbers and Delta=|{:(c_(1),a_(1),b_(1)),(c_(2),a_(2),b_(2)),(c_(3),a_(3),b_(3)):}| , then Delta is

If a_(1),b_(1),c_(1),a_(2),b_(2),c_(2) "and" a_(3),b_(3),c_(3) are three digit even natural numbers and Delta=|{:(c_(1),a_(1),b_(1)),(c_(2),a_(2),b_(2)),(c_(3),a_(3),b_(3)):}| , then Delta is
