Jack, Kay and Lynn deliver flyers in a small town. If each person works alone, it takes Jack 4 hours to deliver all the flyers, and it takes Lynn 1 hour longer than it takes Kay. Working together, they can deliver all the flyers in 40% of the time it takes Kay working alone. How long does it take Kay to deliver all the flyers alone?

Well, it is pretty hard to type here. I'll put it in words. Hope you get it.

Left hand side (LHS) of the equation:
x to the power √x³ to the power ³√x

Right Hand Side (RHS) of the equation:
(x√x)^(x)


Now, find the sum of the positive roots of the equation.
