MR은 코시국에서 방역수칙을 잘 지키면서 오늘도 열심히 생활하고 있다,
그. 런. 데..!!
요즘 cho라는 사람이 MR의 방역수칙을 방해하고 있다,
그래서 MR은 보안철저 특선 옥에 cho를 가두었다,
MR은 cho에게 5개의 힌트를 주고 그 자리를 떠났다,
힌트는 아래의 이것들 이다,
1: 비번은 4자이다,
2; 번호 하나는 간단한 이차방정식 1,2의 답의 합이다
,( 간단한 이차방정식 문제도 풀고, [ 그네공식 사용가능 ] 감옥탈출기 문제도 풀고, 일석 이조이다,)
3: 배열 123456789와 배열 978865241를 각각 위아래에 배치 한 뒤,
그런 뒤, 두 배열에 첫번째 수와 4번째, 7번째 9번째 수를 모두 더한 뒤,
나누고, 나눴을 때,나온 나머지의 값이다,
4: 3의 제곱근과 5의 제곱근의 값의 숫자의 합이다,
5: ax2 +bx+c =0
이 방정식에서 a를 양수라 할때,
다음의 방정식을 풀고, 풀면 나오는 값이다, ( 이 방정식은 근의 공식이라 값이 식처럼 나온다,)
힌트를 보고 비번의 값을 구하시오,
