There are no denominators which could equal zero.
There are no roots with even indices to cause any non-real results.

Therefore all real numbers can be substituted for x.

That's what the domain is, the set of all numbers that can be
substituted for x, so the domain is "ALL REAL NUMBERS", which 
is sometimes a fancy R like R,
