1?
3^1 = 3 Rem = 3
3^2 = 9 Rem = 1
3^3 = 27 Rem = 3
3^4 = 81 Rem = 1
....
3^50/4 - Rem = 1
Just a check 3^50 = 717897987691852588770249 (of course I used the calc!  )
Reminder should be 1.

1=> 3/4 => 3
2=> 9/4 => 1
3=> 27/4 => 3
for even n rem =3 and odd rem=1 50 is even rem=3

these are the units
3^1=3
3^2=9
3^3=7
3^4=1
3^50=9 9/4==remainder 1

3^1/4 = 3/4 - R3
3^2/4 = 9/4 - R1
3^3/4 = 27/4 - R3
3^4/4 = 81/4 - R1
Even powers always give R1.
So 3^(50)/4 will give a remainder of 1
As for the question where we went, I'm not sure about the rest, but I was busy with work, recovering from a neck strain and relaxing over the weekends !!
