Kindly explain in words the problem and solution shown in the picture.

5 = -26 mod (31)
-2न mo d (31)
3 = - 28 mod (31)
- 29
mod (31)
-30 mad (31)
If
9 E6 mad (m) and
C =d mod (m)
then
ac E bd mod (m)
So,
5.4.3. 2.) = (26)(-27)(-28) (-29)(-30) mod 31
> 5! E(u20)(27)(2s)(29) (30) mad(31)
=>
» 5. 25! =H°(30! mod (31)
125, = 25! mod
= 25! mod (31)
From wilsons Theorem. pis
prime then,
(P-1)! = -1 med (P)
is prime
31
30! = -1 mod (31)
Hence ,
= fIjo (-+) mod(31)
5,25!
