This is a question from our test ?? if yes it should be created by the former mod........and we are having some problem to figure them out and fade out.



Back to the question.

First of all b and c are not the same.

B is \(\frac{b!}{(ac)!}> 0\) if you bring the RHS to the LHS

C is \(\frac{b!}{(ac)!}>\) 1

Now

A) \(\frac{5*4*3*2*1}{5*4*3*2*1} > 0\) that is true 1 > 0

B) \(\frac{5*4*3*2*1}{6*5*4*3*2*1} > 0\) tha is impossible for the test, due to the fact it deals with real numbers and \(\frac{0}{6}\) is infinite. which is not possible in math

All the rest of the answer choices are the same OR impossible OR \(a positive number < 0\) which is impossible as well. Check on your own.

The question is good and sophisticated but we are working to fade out due their complexity and out of scope for the GRE purpose.

Ask anything you need. Even via private message.
