`sqrt(x+2) gt sqrt(8-x^2)`

lim_(x rarr1)(sqrt(x^(2)+8)-sqrt(10-x^(2)))/(sqrt(x^(2)+3)-sqrt(5-x^(2)))=

y=Tan^(-1)((sqrt(1+x^(2))+sqrt(1-x^(2)))/(sqrt(1+x^(2))-sqrt(1-x^(2)))) then find (8ddy)/(8ddx)

which of the following statement(s) is/are CORRECT? I. (sqrt(11) + sqrt(2)) gt (sqrt(8) + sqrt(5)) II. (sqrt(10) + sqrt(3)) gt (sqrt(7) + sqrt(6))

Degree of the polynomial [sqrt(x^(2)+1)+sqrt(x^(2)-1)]^(8)+[(2)/(sqrt(x^(2)+1)+sqrt(x^(2)-1))]^(8) is.

Solve : (sqrt(2+x) + sqrt(2 - x))/(sqrt(2 +x) - sqrt(2-x)) =
