SOLVED:Big- O, big-Theta, and big-Omega notation can be extended to functions in more than one variable. For example, the statement f(x, y) is O(g(x, y)) means that there exist constants C, k1, and k2 such that |f(x, y)| ≤C|g(x, y)| whenever x>k1 and y>k2. Show that (x^2 x y x logy)^3 is O(x^6 y^3).
