Hello,

Keep in mind Wilson's Theorem :

We know by the theorem that .

But . Hey ! and

So we have

--> , where a is the inverse of 2 modulo 67, and such that

One can see that

Therefore

b. 31!/22!=n and m=11

Let me think about it

See the first part of a/Also,

Prove that if p is an odd prime number, then 2(p-3)! congruent to -1modp

(p-1)!=(p-3)!*(p-2)*(p-1)

I hope the wedding was okI missed class due to a wedding and our book only states wilson's theorem...so im really confused..thanks for any help1
