30(x+2)/(sqrt(4x-x^(2)))

int(sqrt(2+x^(2))-sqrt(2-x^(2)))/(sqrt(4-x^(4)))dx

The value of lim_(xto2) (((x^(3)-4x)/(x^(3)-8))^(-1)-((x+sqrt(2x))/(x-2)-(sqrt(2))/(sqrt(x)-sqrt(2)))^(-1))" is "

Evaluate lim_(x rarr2)(sqrt(x-2)+sqrt(x)-sqrt(2))/(sqrt(x^(2)-4))

lim_(x rarr 2) (sqrt(x-2) + sqrt(x) - sqrt(2))/(sqrt(x^(2) - 4)) is equal to :

lim_(x rarr2)(sqrt(x-2)+sqrt(x)-sqrt(2))/(sqrt(x^(2)-4))

lim_(x rarr2)((sqrt(x^(2)-4x+5)-1)((x+2)^(9/2)-512))/((x-2)(sqrt(x^(2)-4x+20)-4))

lim_(xto oo)(sqrt(4x^(2)+2x+1)-sqrt(4x^(2)+1)) is

Lt_(x to oo) (sqrt(3+9x^(2))+sqrt(4x^(2)-1))/(sqrt(1+16x^(2))-sqrt(9x^(2)+2))=

Show that Lt_(x to-2) sqrt(x^(2)-4)=0= Lt_(x to 2) sqrt(x^(2)-4)
