<p>Suppose I have a utility function of Cobb-Douglas form </p>

<p><span class="math-container">$$U(x, y) =x^{0.2}*y^{0.8}$$</span></p>

<p>I want to describe it in words. I would say like:</p>

Suppose I have a utility function of Cobb-Douglas form

$$U(x, y) =x^{0.2}\*y^{0.8}$$

I want to describe it in words. I would say like:

Is this correct and conprehensive?
Any help will be appreciated.
