#sqrt(125/2)=sqrt(125)/sqrt(2)=sqrt(25xx5)/sqrt2=(sqrt(25)xxsqrt(5))/sqrt2=(5sqrt5)/sqrt2#

If "simplify" means you also need to rationalize denominators (it usually does mean this), continue:

#=(5sqrt5)/sqrt2sqrt2/sqrt2=(5sqrt10)/2#

Alternatively:

#sqrt(125/2)=sqrt(125)/sqrt(2)=sqrt(125)/sqrt2sqrt2/sqrt2=sqrt250/2=sqrt(25xx10)/2=(5sqrt10)/2#
