bug#73561: Couple of typos in the documentation

[zvavybir]

Package: guile
Version: 3.0.10
Severity: minor
Tags: patch

There are a couple typos of missing brackets/parentheses in the documentation 
(for example in the PDF on page 127 under integer-expt or in the first code 
block of page 601).

As I don't know texinfo (only (La)TeX), I don't know if this patch is correct, 
but at least it should be trivial for someone who knows what they're doing to 
write a correct one based on it:

 In addition to the classification into integers, rationals, reals and
 complex numbers, Scheme also distinguishes between whether a number is
 represented exactly or not.  For example, the result of
