[x=(5)/(9)quad y=(9)/(11)],[|x|xy|=|x|times|y|]

If x=5/9 and y=9/11 then prove that |x xx y|=|x| xx| y|

If x-y= (x+y)/(9)= (xy)/(6) then value of xy= ?

Add the following (8)/(5)x+(11)/(7)y+(9)/(4)xy,-(3)/(2)x-(5)/(3)y-(9)/(5)xy

If (2)/(x) + (3)/(y) = (9)/( xy ) and (4)/(x) + (9)/(y) = (21)/(xy) where x ne 0 and y ne 0, that what is the value of x + y ?

When x=5 and y=2 , the expression (xy)/(70)+(9)/(5(x+y))+(1)/(x+y)=?

(x^(3))/(9y^(2))times(27y)/(x^(5)) =____.

Find the products: ((3)/(x)-(5)/(y))((9)/(x^(2))+(25)/(y^(2))+(15)/(xy))

Evaluate: [(x^(5y-5)xx x^(5-2y))/(x^(4y-6)xx x^(2y-9))]^(-(4)/(3))
