7+4sqrt(3);sqrt(x)-(1)/(sqrt(x))

int ((log(1+6sqrt(x)))/(3sqrt(x)+sqrt(x))+(1)/(3sqrt(x)+4sqrt(x)))dx

find x: (sqrt(x+1)+sqrt(x-1))/(sqrt(x+1)-sqrt(x-1))=3/7

lim_(x rarr1)(13sqrt(x)-7sqrt(x))/(5sqrt(x)-3sqrt(x))

The value of f(x,y)=((4sqrt(x^(3)y)-4sqrt(x^(3)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/(4sqrt(xy)))^(-2)(1+2sqrt((y)/(x))+(y)/(x))^((1)/(2)) when x=9,y=0.04

(1)/(sqrt(x+3)-sqrt(x-4))

If x= (2sqrt(10))/7 find the value of (sqrt(1+x)+sqrt(1-x))/(sqrt(1+x)-sqrt(1-x))

If x = 7 - 4 sqrt(3) , then sqrt(x) + (1)/(sqrt(x)) is equal to
