Answer:

1/2

Explanation:

Find the following limit:

lim_(x->∞) (x + 1)/(1 x + sqrt(x)^2 + 1)

(x + 1)/(1 x + sqrt(x)^2 + 1) = (x + 1)/(2 x + 1):

lim_(x->∞) (x + 1)/(2 x + 1)

The leading term in the denominator of (x + 1)/(2 x + 1) is x. Divide the numerator and denominator by this:

lim_(x->∞) (1 + 1/x)/(2 + 1/x)

The expressions 1/x and 1/x both tend to zero as x approaches ∞:
