그냥 작도 문제임.

문제 1: 어떤 원과, 그 원의 중심이 종이에 그려져 있다. 넓이가 이 원의 2배인 원을 작도하시오. (방법을 알기 쉽게 1번, 2번, 3번... 로 번호를 붙여서 설명하거나 그림을 그려 주세요. )

문제 2: 어떤 원과, 그 원의 중심이 종이에 그려져 있다. 넓이가 이 원의 3배인 원을 작도하시오. (방법을 알기 쉽게 1번, 2번, 3번... 로 번호를 붙여서 설명하거나 그림을 그려 주세요. )

루트2와 루트3을 작도하라는 거 아닌가요? 불가능하지 않나요?

  $\sqrt[3]{n}$ 을 작도하는 것은 불가능하다는 것이 증명되었습니다. (n이 특정 수일 때는 빼고) 하지만 그냥 $\sqrt{n}$ 은 작도할 수 있습니다.
