Answer 1

Step-by-step explanation:

answer is 0.64.by this above process you can understand

Answer 2

ANSWER= XY=9.

Explanations:

It is given that

√(x/y)+√(y/x)= 10/3

multiply each term by (√xy) we get.

x+y=(10/3)√xy

10=(10/3)√xy[from(1)]

10×(3×10)=√xy

3=√xy

square on both the side of equation

9=xy

Therefore

xy=9
