I have added the following clarification for Carmin. It is reproduced here in case you are also interested.

...
=(sqrt(5)4*(a(7/2))4) a3-8
=5(1/2)*4*a(7/2)*4*a3-8
=25 a14 a-5
=25 a9

the denominator 2 in the fraction (7/2) is an exponent and not a simple number. This is probably from where you got the 16.

So the 16 is not part of the answer? It's just 25 a^9?

Right!
