If `a/b+b/a=1` then `a^3+b^3` is equal to

Let A=[(-4, -3, -3),(1, a, 1),(4, b, 3)] and A=A^(-1) , then a+2b is equal to

If a+b+c=0, then a^(3)+b^(3)+c^(3) is equal to

If a/b+b/a=\ -1, then a^3-b^3=? (a)1 (b) -1 (c) 1/2 (d) 0

If a/b+b/a=1, then a^3+b^3=? (a) 1 (b) -1 (c) 1/2 (d) 0

If a ,b ,and c are in A.P., then a^3+c^3-8b^3 is equal to (a). 2a b c (b). 6a b c (c). 4a b c (d). none of these

If A and B are two events such that P(A) = 1/2 , P(B) = 1/3 and P(A//B) =1/4 then P(A cap B) is equal to

If a+b+c=2,a^(2)+b^(2)+c^(2)=1 and abc = 3 then 1/a+1/b+1/c is equal to

If in DeltaABC , a=2b and A=3B, then A is equal to

If a binary operation * is defined by a * b=a^2+b^2+a b+1 ,then (2 * 3) * 2 is equal to (a) 20 (b) 40 (c) 400 (d) 445

If P(A) =1/2 ,P(B) =3/5 and P (A cap B) = 3/10 then P(B/A) is equal to
