If `x=(-1+isqrt3)/2` then the value of `x^2+x+1` is
(a) 2
(b) 1/2
(c) 0
(d) 1

Find the value of x if 2^(x-3)=1 (a) 1 (b) 2 (c) 3 (d) 4

If (x-1)/(x)=3, then the value of 1+(1)/(x^(2)) is (a) 9(b) 10(c)11 (d) None of these

If f(x)=lim_(n->oo)((x^2+a x+1)+x^(2n)(2x^2+x+b))/(1+x^(2n))and lim_(x->+-1)f(x) exist, then The value of b is (a)-1 (b). 1 ( c.) 0 (d).2

If x+y=2a then the value of (a)/(x-a)+(a)/(y-a) is (a) 2 (b) 0(c)-1 (d) 1

1.If |[2x,-1],[4,2]|=|[3,0],[2,1]| ,then value of x is (a) 3 (b) 2/3 (c) 3/2 (d) -1/4

If |(x , 1),(1,x)| = |(2 , 0),(8,4)| then value of x is: (a) pm 3 (b) pm2 (c) pm4 (d) 0

Let x , y be two variables and x >0, x y=1 , then minimum value of x+y is (a) 1 (b) 2 (c) 2 1/2 (d) 3 1/3

The Tangent to the curve y=x+(1)/(x) at (a,b) is parallel to X - axis , then the value of : (a,b)= (a) (0,+-1) (b) (+-2,+-3) (c) (+-1,0) (d) (+-1,+-2)

if x=(sqrt2 + 1 ) ^(-1//3) , then the value of (x^3 - frac(1) (x^3)) is (A) 0 (B) -sqrt2 (C ) -2 (D) 3sqrt2

If 2x=-1+sqrt(3)i, then the value of (1-x^(2)+x)^(6)-(1-x+x^(2))^(6) is 32(b)-64 (c) 64(d)0
