I would like some help with the following calculus

0 0, x, > 0. 3. For the Cobb - Douglas production function f(x,, x, ) = Ax, x; , with A > 0, c, B > 0defined on R. , show that Euler's Theorem applies. 4. Show that the following functions are homothetic but not homogeneous. (i) f (x, , x2 ) = k + x xx for k = 0a constant. ( 1) f ( x,,x 2 ) =ex 5. Illustrate Euler's Theorem for the Cobb - Douglas production function !A0
