tim m;n thuoc N sao cho m^2+2 la so nguyen to va 2m^2=n^2_2
tim m thuoc N sao cho m^2 + 2014 la so chinh phuong
tim m,n thuôc Z de 1/m + n/6 = 1/2
tim m,n thuoc N de m/2 - 2/n = 1/2
tim n thuoc z sao cho M=3N+4/N-1 co gtri nguyen
Bai1 a,cho n thuoc N. Chung minh rang 6n+5 va 4n+3 la 2 so nguyen to cung nhau
b, tim so nguyen x sao cho x+2016 la so nguyen duong nho nhat
tim x , y thuoc n de 2^x-2^y=2016
tim n thuoc N sao cho n^2+7n+2 chia het cho n+4
tim n thuoc Z sao cho n+13 chia het cho n-2
tim m,n thuoc z de 1/m+n/6=1/2
