Summary:  1/sqrt(8) - sqrt(8) / 8 --/---> 0

Initial Comment:
(%i17) 1/sqrt(8) - sqrt(8) / 8;
(%o17) 1/(2*sqrt(2))-1/2^(3/2)

(%i18) expand(%,0,0);
(%o18) 0

Here I think (%o17) is unsimplified--the expand(%,0,0)
shouldn't be required.

Message:
With revision 1.80 of simp.lisp the example simplifies as expected:

(%i14) 1/sqrt(8) - sqrt(8) / 8;
(%o14) 0

Closing this bug report as fixed.

Also:

(%i45) sqrt(8) / 8;
(%o45) 1/2^(3/2)

(%i46) expand(%,0,0);
(%o46) 1/(2*sqrt(2))
