I don't think that's the issue: he's already successfully written a couple of functions using this template. Problem 11.5.3 says "develop the function exponent ... Eliminate * from this definition too." The natural-number template is fine for putting together the right number of x's, but how do you multiply the (not necessarily natural) x's together without * ?
