" If "x+y=10" ,then find the maximum value of "xy" ."

if 2x+y=1 then find the maximum value of x^(2)y

if x+y=10 , thent he maximum value of xy is

if x+y=10 , thent he maximum value of xy is

If x+y=1 then find the maximum value of the function xy^(2)

If x+y=1 then find the maximum value of the function xy^2

If x+y=a then find the maximum value of the function xy^(2)

If x+y =12 what is the maximum value of xy?

If x + y=5 , then find the greatest value of 10xy.

If log_(10)(x^(3)+y^(3))-log_(10)(x^(2)+y^(2)-xy)<=2, where x,y are positive real number,then find the maximum value of xy.
