find the remainder of 32^32^32 when divided by 9

• 32 = 2⁵
  (2⁵)³² = 2¹⁶⁰
  (2¹⁶⁰)³² = 2⁵¹²⁰
  You are looking for the remainder of 2⁵¹²⁰ ÷ 9.
  
  2¹ mod 9 = 2
  2² mod 9 = 4
  2³ mod 9 = 8
  2⁴ mod 9 = 7
  2⁵ mod 9 = 5
  2⁶ mod 9 = 1
  2⁷ mod 9 = 2
  2⁸ mod 9 = 4
  2⁹ mod 9 = 8
  2¹⁰ mod 9 = 7
  2¹¹ mod 9 = 5
  2¹² mod 9 = 1
  ...
  Note that the pattern repeats, and when the exponent is divisible by 6, the remainder is 1.
  5120 = 6(853) + 2, therefore
  2⁵¹²⁰ mod 9 = 4
