20*(x+2)/(sqrt(4x-x^(2)))

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

(1)/(sqrt(x^(2)-8x-20))

lim_(x rarr2)(sqrt(x^(3)-4)-2)/(sqrt(20-x^(2))-4)

Integrate the following with respect to x. (1)/(sqrt(4x^(2)-20x+34))

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))

If x+sqrt(x^(2)-1)+(1)/(x+sqrt(x^(2)+1))=20 then x^(2)+sqrt(x^(4)-1)+(1)/(x^(2)+sqrt(x^(4)-1))=

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