Prove Euler's Theorem: Suppose that g:RK+2R g: \mathbb{R}^{K+2} \rightarrow \mathbb{R} is differentiable in xR x \in \mathbb{R} and yR y \in \mathbb{R} with partial derivatives denoted by gx g_{x} and gy g_{y} , and is homogeneous of degree m m in x x and y y . Then

mg(x,y,z)=gx(x,y,z)x+gy(x,y,z)yxR,yR, and zRKm g(x, y, z)=g_{x}(x, y, z) x+g_{y}(x, y, z) y \quad \forall x \in \mathbb{R}, y \in \mathbb{R}, \text { and } z \in \mathbb{R}^{K}

Moreover, gx(x,y,z) g_{x}(x, y, z) , and gy(x,y,z) g_{y}(x, y, z) are themselves homogeneous of degree m1 m-1 in x x and y y .

Solve with each and every step, do not skip any step

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
