xac dinh so nguyen x de x^2-3/x^2-1 la so nguyen
Tim so nguyen a de so huu ti x=-101/x+7 la 1 so nguyen
tim x nguyen de \(\frac{2012\sqrt{x+5}}{1006\sqrt{x+1}}\)la so nguyen
tim cac gia tri nguyen cua x de gia tri bieu thuc y=2x^2+1/2x-1 la so nguyen
cho A=\(\frac{\sqrt{x}+1}{\sqrt{x}-3}\)(x\(\ge\)0)
tim so nguyen de A co gia tri la so nguyen
Cho so huu ti x=\(\frac{a-3}{2}\)
Voi gia tri nao cua xthi
a ) la so nguyen duong
b) la so nguyen am
c) x ko la duong cung ko am
