While checking my answer to the square root of 171 I noticed wolfram displayed also another function under the listing of "exact answer". It gave 3 with a square root sign then 19. A search on the web yielded three different explanations. One I did not understand the other two as follows:

a) 3* the square root - to be expected

b)The inverse function of a

^{n}- something new I just learned

Needless to say neither of the above appear correct, or wolfram means something completely different.
