Degree of homogeneity of the production function

Hi please help; how do you work out the degree of homogeniety of the following production function

q = l^1/2 k + k^3/2

This is what I think:

This polynomial in 2 variables ( ) is homogenous of degree because if we add the exponents of the variables of each term we get for the first term and also for the second term.

Thanks got it.
