nalin [4]

The number of pieces per stack after 3 cuts represented by a power expression can be written as 3^{3}

  • Thus we have number\: of \:equal\: pieces^{number\: of \:cuts}

  • After 1 cut ; 3^{1} = 3
  • After 2 cuts ; 3^{2} = 3\times3 = 9
  • After 3 cuts ; 3^{3} = 3\times3\times3 = 27

Therefore, the Number of pieces present in stack after 3 cuts is 3^{3}
