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)=1(b)-1 (c) (1)/(2)(d)0

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

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

If a b c = 0, then ({(x^a)^b}^c)/({(x^b)^c}^a) = (a)3 (b) 0 (c) -1 (d) 1

If a = - 2 , b = -1 , then ( a^b - b^a ) is equal to ( a ) -1 ( b ) 0.5 ( c ) -2 ( d ) -1.5

If x+2 is a factor of x^2+a x+2b and a+b=4 , then (a) a=1, b=3 (b) a=3, b=1 (c) a=-1, b=5 (d) a=5, b=-1

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

If a=3^(-3)-3^3\ a n d\ b=3^3-3^(-3),\ t h e n a/b-b/a (a) 0 (b) 1 (c)-1 (d) 2

If a=2b, then a:b=2:1 (b) 1:2( c) 3:4 (d) 4:3

If a b+b c+c a=0 , then what is the value of (1/(a^2-b c)+1/(b^2-c a)+1/(c^2-a b)) ? (a) 0 (b) 1 (c) 3 (d) a+b+c
