If a,b, and c be non-zero real numbers such that
`|{:(1+a,1,1),(1,1+b,1),(1,1,1+c):}|=0" " "then"" "1+1/a+1/b+1/c` is

If a, b and c are non-zero real numbers and |(1+a,1,1),(1,1+b,1),(1,1,1+c)|=0 , then what is the value of (1)/(a) + (1)/(b) + (1)/(c) ?

|{:(1,a,b+c),(1,b,c+a),(1,c,a+b):}|=0

|{:(b+c,a,1),(c+a,b,1),(a+b,c,1):}|=0

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

If a ,b and c are all non-zero and |(1+a,1,1),( 1,1+b,1),(1,1,1+c)|=0, then prove that 1/a+1/b+1/c+1=0

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

If |(a,1,1),(1,b,1),(1,1,c)|=0 then show that 1/(1-a)+1/(1-b)+1/(1-c)=1

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

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
