If underset(x to oo)lim (sqrt(x^(2)-ax)-x)=1/2" then a="

If underset( x rarr oo) ( "lim") (( x^(2) + x+ 1)/(x+1) -ax -b) = 4 , then

Evaluate underset( x rarr oo )("lim") ( sqrt( 3x^(2) - 1) - sqrt( 2x ^(2) - 1))/( 4x + 3)

If Lim_(x rarr a) (sqrt(x-b)-sqrt(a-b))/(x^(2)-a^(2))(a gt b) = 1/64 and Lim_(x rarr oo) (sqrt(x^(2)+ax)-sqrt(x^(2)+bx)) = 2 then the value of a/b, is

lim_ (x rarr oo) (sqrt (x ^ (2) -8x) + x)
