bai 1: Cho cac don thuc A=-4/9x^3y va B= 3/8 x^5y^3. Tim cac cap gia tri (x;y)de A,B cung gia tri am
bai 2: viet don thuc B=64xy^12 duoi dang luy thua cua 1 don thuc voi so mu khac 1
bai 3: cho A=8x^5y^3; B=-3x^6y^3; C=-6x^7y^2. CM: Ax^2+Bx+C>0
a)Cho vi du ve 1 don thuc ,1 da thuc nhung khong phai la don thuc ,2 don thuc dong dang voi nhau ,da thuc 1 bien
b)Hay viet 1 don thuc dong dang voi don thuc don thuc xy\(^3\) sao cho tai x=-1 y=2 gia tri cua don thuc do la so nguyen duong nho hon 10
thu gon don thuc tim bac he so cua da thuc A=x^3 *(-5/4x^2y)*(2/5x^3y^4)
Cho don thuc A=(-2xy)-4/5x^2y^3 a,Thu gon don thuc tren ,cho biet phan he so va phan bien ,tim bac cua don thuc b,Tinh gia trim cua don thuc tai x=1,y=-1
Cho don thuc A=(-2xy)-4/5x^2y^3 a,Thu gon don thuc tren ,cho biet phan he so va phan bien ,tim bac cua don thuc b,Tinh gia trim cua don thuc tai x=1,y=-1
