Giai chi tiet nhe
So 3^50 + 1 co la tich cua 2 so tu nhien lien tiep khong ?
Thanks moi ng , co giai chi tiet vs nha!
4/x+2 + (-3)/x-2 + 12/x^2-4 giai chi tiet ho mk !
giai phuong trinh
(x^2 + 1)^2 + 3x(x^2 + 1) + 2x^2 = 0
(x^2 - 9)^2 = 12x + 1
giai chi tiet gium nha
so sanh a va b trong truong hop sau:
5a+2<5b-1
cac bn giup minh voi
giai chi tiet mot chut nhe
