As "(sqrt (g (a / 2)))" has the form of an expression, rather than a condition, can you clarify what is required?

This is a question from my SAT prep book, im starting to think there was a typo and something was omitted from this question based on your reply.

Perhaps "If $\displaystyle \!\sqrt{g\!\left(\frac{a}{2}\right)\!} = 6$" was intended. If that's the case, $\displaystyle a = \frac{68}{5}$, which is choice D.
Thanks from Inder

I also thought the same thing, Thanks for confirming for me.
