Ta có \(M=n^2+4n-5\)

\(=\left(n+5\right).\left(n-1\right)\)

Để M là số nguyên tố thì n-1=1 <=> n=2

Mark the letter A, B, C, or D on your answer sheet to indicate the word that differs from the other three in the position of the primary stress in each of the following questions.

A. Discuss

B. Waving

C. Airport

D. Often

Đặt \(n^2+4n+2013=k^2\left(k\in Z\right)\) (bạn xem lại đề nhé \(n\in Z\) thì k\(\in Z\) mình phải lấy như vậy vì nếu ko sẽ có nhiều GT của k lắm ko xét được)

\(n^2+4n+2013=k^2\)

\(\Leftrightarrow n^2+4n+4+2009=k^2\)

\(\Leftrightarrow\left(n+2\right)^2+2009=k^2\)

\(\Leftrightarrow k^2-\left(n+2\right)^2=2009\)

\(\Leftrightarrow\left(k-n-2\right).\left(k+n+2\right)=2009\)=-1.(-9)=1.9

Do (k-n-2)<(k+n+2) nên ta có:

\(\left\{{}\begin{matrix}k-n-2=1\\k+n+2=2009\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}n=1002\\k=1005\end{matrix}\right.\)

hoặc \(\left\{{}\begin{matrix}k-n-2=-2009\\k+n+2=-1\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}n=1002\\k=1005\end{matrix}\right.\)

Vậy n=1002
