p nhỏ nhất = 5 => p + 8 = 13
Vậy p + 100 = 5 + 100 = 105
Vậy p + 100 là hợp số
mình nghĩ không còn cách nào khác đâu
Cho p va p + 8 deu la so nguyen to (p>3 ). hoi p =100 la so nguyen to hay hop so
cho P va P+8 la 1 so nguyen to (P>3) hoi P+100 la so nguyen to hay hop so chi tiet
cho p la so nguyen to lon hon 3. Biet 8p+1 va p deu la so nguyen to (p lon hon 3).Hoi p+100 la so nguyen to hay hop so
Cho p va 2p+1 la cac so nguyen to (p>5).Hoi 4p+1 la so nguyen to hay hop so
cho M=a^100+b^100+c^100+d^100 trong do a,b,c,d la cac so nguyen to khac 0 hoi M la so nguyen to hay hop so
Cho p la so nguyen to (p<3) va 2p+1 cung la so nguyen to . Hoi 4p+1 la so nguyen to hay hop so?Vi sao?
Cho P va 8P-1 la so nguyen to (p>3)
Hoi 8P+1 la so nguyen to hay hop so.
cho n la so nguyen to lon hon 3. hoi n^2 la nguyen to hay hop so. ai lam loi giai va lam dung la duoc tich
