F(k,l)=K(squared) + L(squared)
SOMEONE PLEASE HELP---
In general, $\displaystyle f(\lambda t, \lambda y) = \lambda^\alpha f(t,y)$ for some real number $\displaystyle \alpha \implies$ f is a homogeneous function of degree $\displaystyle \alpha \in \mathbb{R}$.
$\displaystyle f(\lambda k, \lambda l) = (\lambda k)^\frac{1}{2} + (\lambda l)^\frac{1}{2} = \lambda^\frac{1}{2}(k^\frac{1}{2} + l^\frac{1}{2}) = \lambda^\frac{1}{2}\cdot f(k,l)$.
I've shown you the general method to determine whether a function is homogeneous, and if it is of what degree. It's hard trying to figure out if this is truly what you're wanting, as you never state the question.
I'd like to emphasize that you will never understand this material if you rely on someone else to do all the work for you.
he just said to introduce 'z' (which is greater than one) and solve(by introducing 'z')------yeah i know i have to learnthis stuff but now its like chinese----i got someone helping me next week with a refresher course--but now i have to do these problems somehow and dint know where to begin, so ANY help is greatly appreciated--THANKX---
