`lim_(x rarr -oo)sqrt(x^2+1)+x` is

Evaluate the following limit : lim_(x rarr oo)(sqrt(x^2+x+1)- sqrt(x^2+1)) .

lim_(x rarr oo) sqrt(x^(2)+1)- sqrt(x^(2)-1) = a)-1 b)1 c)0 d)2

Evaluate the following limit : lim_(x rarr oo)(sqrt(3x^2-1)+ sqrt (2x^2-1))/(4x+3) .

lim_(x rarr oo) (sqrt(x^(2) + 1) - root(3)(x^(3) + 1))/(root(4)(x^(4) + 1) - root(5) (x^(4) + 1)) equals :

Evaluate: lim_(x rarr oo)sqrt(x^(2)+x+1)-x

lim_(x rarr oo)(sqrt(x^(2)+x)-x)

Show that lim_(x rarr oo)(sqrt(x^(2)+x+1)-x)!=lim_(x rarr oo)(sqrt(x^(2)+1)-x)

lim_(x rarr+oo)x(sqrt(x^(2)+1)-x)

lim_ (x rarr-oo) [sqrt (x ^ (2) + x + 1) + x] =
