`(sqrtx+sqrty) * (sqrtx-sqrty)`

int (1/sqrtx-sqrtx)dx

y= log(sqrtx+1/sqrtx)

If x,y in R satisfy the equation x^2 + y^2 - 4x-2y + 5 = 0, then the value of the expression [(sqrtx-sqrty)^2+4sqrt(xy)]/((x+sqrt(xy)) is

lim_(xrarr0^+) (sqrtx)/(sqrt(4-sqrtx)-sqrtx)

int e^(sqrtx) dx

Solve the system of equation 2^(sqrtx+sqrty)=256 and log_10sqrt(xy)-log_10(3/2)=1 .

int (a^sqrtx)/(sqrtx) dx equals

lim_(xrarroo) (sqrt(x+sqrt(x+sqrt(x)))) - sqrtx

int_(a^4)^(b^4)(f(sqrtx))/((sqrtx)[f(a^2+b^2-sqrtx)+f(sqrtx)])dx is equal to

int_(a^4)^(b^4)(f(sqrtx))/((sqrtx)[f(a^2+b^2-sqrtx)+f(sqrtx)])dx is equal to
