Simplifying mathematical expression containing log and product in Maxima

Question

I wonder how to simplify this expression in Maxima.

log(product (exp(-(1/%lambda)*(x[i] -\mu)^a), i, 1, n));

Edit

The following code is not simplifying the expression

expand(log(product (exp(-(1/%lambda)*(x[i] -\mu)^a), i, 1, n)));

Is there any other possibility?

I know how to solve the expression but I want to do this in Maxima.

Answer 1

Try ev(foo, logexpand=all) or ev(foo, logexpand=super) where foo is the product you stated. Try ? logexpand to see some documentation (incomplete, however).
