simplifying symbolic expressions with factors of pi

If I have some symbolic expression say
FF = besselj(1/2,x)
FF = (2^(1/2)*sin(x))/(pi^(1/2)*x^(1/2))
I wish to cancel this factor of pi^(1/2) however if I do
GG = FF*pi^(1/2)
then I will get an expression that still has the factor of 1/pi^(1/2) but also a numeric approximation to pi^(1/2) multiplied by it.
How does matlab hold this "symbolic" pi value, since clearly normal pi is just a dp variable and how do I cancel it in expressions?
