Câu 7b, \(3+\dfrac{4}{7}=\dfrac{3}{1}+\dfrac{4}{7}=\dfrac{21}{7}+\dfrac{4}{7}=\dfrac{25}{7}\)(bn đặt tính sai r)
Sửa tới đó thôi lười qá :v, từ câu 1 đến câu 7 bn sai chừng đó đó :v, còn lại đúg r :v
nếu p = 2 ta có : p + 2 = 2 + 2 = 4 (loại)
nếu p > 2 vì p là số nguyên tố mà p> 2 nên p là số lẻ => p = 2k + 1 (k\(\ge\)1)
=> p + 1 = 2k + 1 + 1 = 2k + 2 = 2.(k+1) (loại)
vậy không có giá trị nào của p thỏa mãn đề bài
