Question

if √x/y + √y/x =10/3 then find xy​

Answer 1

Step-by-step explanation:

root x/y+ root y/x=10/3

root x × x+root y×y/xy=10/3

root x×x+root y×y×3/10=xy.

Answer 2

If u square on both side it will become (x/y)+(y/x)+1=100/9 then take lcm so it becomes (x^2+y^2+xy)/xy=100/9. So the ans becomes 9*x^2+9*y^2+9*xy=100xy and then

(9*x^2+9*y^2)/91=xy
