Hi,
Avoiding discussion on correct transformations towards simpler expressions in general, here is an advise on your particular example.
You can use susb method with wildcards to make manual transformation
pow(X,1/2)*pow(Y,1/2) -> pow(X*Y,1/2)
Also, with square roots it will be better to use possymbol instead of realsymbol whenever possible. This even can make the desired transformation automatically through the expand method. (the desired answer is not correct for arbitrary reals, indeed)
Best wishes, Vladimir
