Question

If root(x/y)+root (y/x)=10/3 and x+y=10 then the value of xy is

Answer 1

Hi ,

It is given that ,

x + y = 10 -----( 1 )

√( x/y ) + √( y/x ) = 10/3

multiply each term with ( √xy ), we get

x + y = (10/3)√xy

10 =( 10/3 )√xy [ from ( 1 ) ]

=> 10 × (3/10) = √xy

3 = √xy

square on both sides of the equation,

9 = xy


Therefore ,

xy = 9
