1) I very like snacks.

2) I sometimes eat snack, because I don't have money to buy a lot of them.

3) I choose snacks from brands like Oishi or Orion.

4) I don't think that. Because snacks have a lot of energy and other, which makes you fat or high cholesterol, or tooth decay.

5) No. In my country, people only eat two kind of snacks - chips and sticks.

CHÍCH NHAU LÀ XẤU! TINH TRÙNG MÀU TRẮNG!

( XEM TRÊN ANIME )

Đặt \(a=\frac{1-\sqrt{5}}{2},b=\frac{1+\sqrt{5}}{2}\)

Ta có \(a+b=1,a-b=-\sqrt{5},ab=-1\)

Ta sẽ tính từ từ. Cụ thể

\(a^2+b^2=\left(a+b\right)^2-2ab=3\)

\(a^2-b^2=\left(a+b\right)\left(a-b\right)=-\sqrt{5}\)

\(a^4+b^4=\left(a^2+b^2\right)^2-2\left(ab\right)^2=7\)

\(a^4-b^4=\left(a^2+b^2\right)\left(a^2-b^2\right)=-3\sqrt{5}\)

\(a^8+b^8=\left(a^4+b^4\right)^2-2\left(ab\right)^4=47\)

\(a^8-b^8=\left(a^4+b^4\right)\left(a^4-b^4\right)=-21\sqrt{5}\)

\(a^{16}-b^{16}=\left(a^8+b^8\right)\left(a^8-b^8\right)=-987\sqrt{5}\)

22=2x11

1+1=2

k cho mình nhá

Số gà:22

Số chó :14

giup nha ! day la bai cua e mink nhung mink ban! giups dc mink k nha!

chị mún lắm nhưng hết lượt rùi

x=109-107

x=2

sai rồi nè thấy chưa, làm thì làm cho đúng chớ Huy Hoàng ngu vcl
