" X15.हल Do it : "quad x-y=13=sqrt(x)+sqrt(y)

y=sqrt(x+sqrt(x))

sqrt(x/y) + sqrt(y/x) = 6

y=sqrt(x+sqrt(x+sqrt(x)))

(x - y) / (sqrt(x)- sqrt(y)) = ____

If x, y, z are in A.P then 1/(sqrt(x) + sqrt(y)) , 1/(sqrt(z) + sqrt(x)) , 1/(sqrt(y) + sqrt(z)) are in

If 0

If 0 (a) sqrt(x)-\ sqrt(y)=\ sqrt(x-y) (b) sqrt(x)+\ sqrt(x)=\ sqrt(2x) (c) xsqrt(y)=ysqrt(x) (d) sqrt(x y)=\ sqrt(x)\ sqrt(y)

Write the middle term (s) of (i) ((y sqrt(x))/(5)-(5)/(x sqrt(y)))^(12)(ii)(2x-(3)/(x))^(15)

15th term in the expansion of (sqrt(x)-sqrt(y)^(17) is :

Suppose that, log_(10) (x-2) + log_(10) y=0 and sqrt(x)+sqrt(y-2)=sqrt(x+y) . Then the value of (x + y) , is
