Please Simplify:
(root5 a^7/2)^4 a^3/a^8
I am having a hard time figuring where to start on this problem. Can someone please help me?

(sqrt5)^4=25
(a^7/2)^4=(a^3.5)^4=a^14
a^14 *a^3*a^8=a^9
check my thinking. 
Not too sure if that is correct. This is what I got.
= (sqrt (5)4*(a (7/2)) 4) a38
=5(1/2)*4*a (7/2)*4*a38
=25 a14 a5
=25 a9
Is this correct?
