If `x+y=7, xy=15` then `x^3+y^3=`

If (x+y)=8 and xy=15 then the value of (x^3-y^3) is :

If x- y = 7 and x^(3) - y^(3) = 133. find : xy

If x + y = 7 and xy = 10, then the value of x^3+y^3 is: यदि x + y = 7 तथा xy = 10 है, तो x^3+y^3 का मान क्या होगा ?

If 4x - 3y = 7xy and 3x + 2y = 18xy , then (x,y) =

If x:y=3:7, then find (7x+3y):(9x-3y)
