수파는 포포즈 문제를 풀다가 또 재미있는 문제를 생각해냈다.

바로 '파이브파이브즈' 였다.

이건 포포즈와는 다르게 5을 5개 써서 수를 만드는 거였다.

(1)사칙연산,루트만 사용 가능하다고 할 때, 모든 수를 다 만들 수는 있을까?

(2)이번에는 식스식스즈다. 사칙연산,루트만 사용 가능하다고 할 때, 모든 수를 다 만들 수 있을까?

(3)모든 수를 다 만들 수 있는 xx즈는 규칙이 있을까?

이 문제 어떠셨나요?

글쎄요

    '모든 수'는 정수 전체를 의미하나요?

      아, 그렇네요.

      지금 조건 추가!

      포포즈면 4^4^4^4까지, 파이브파이브즈면 5^5^5^5^5까지 만들수 있냐를 묻는 걸로 하겠습니다.
