If `a-b=1` , then the value of `a^3-b^3-3a b` will be `-3` (b) `-1` (c) `1` (d) 3

If a=-1, b=-2/3, c=-3/4 , then the value of a+b+c is

If a + b + 1 = 0, then the value of (a^(3) + b^(3) +1 -3ab) is

If A=[a b c b c a c a b],a b c=1,A^T A=I , then the value of a^3+b^3+c^3 can be 3 (2) 0 (3) 1 (4) 4

If a+b+c=8, then the value of (a-4)^(3)+(b-3)^(3)+(c-1)^(3)-3(a-4)(b-3)(c-1) is

"If A"= ({:(2, 3),(5, 1):}), B = ({:(a, b),(c, d):}) and AB = -13I, then find the value of a + b - c + d. (a) 5 (b) 3 (c) 2 (d) 1

If a+b=2c, then the value of (a)/(a-c)+(b)/(b-c) is (1)/(2)(b)1(c)2(d)3

If (a-b)=3,(b-c)=5 and (c-a)=1 then the value of (a^(3)+b^(3)+c^(3)-3abc)/(a+b+c) is?
