1 There’s some (ham / butter / eggs) in the fridge.

2 There aren’t any (potatoes / rice / onions) in the cupboard.

3 I’d like an (orange / apple / banana), please.

4 Is there any (cakes / water / salt )on the table?

5 He wants some( pork / grape / beef) from the supermarket.

6 I’m afraid there isn’t any (prawns / tuna / salmon).

7 Are there any (mushrooms / vegetables / cheese )on the pizza?

8 Do we need a (lemon / egg / carrot) for this recipe?

Lời giải:

$\frac{5}{14}+\frac{-6}{17}+\frac{17}{41}+\frac{9}{14}+\frac{-24}{41}$

$=(\frac{5}{14}+\frac{9}{14})+\frac{-6}{17}+(\frac{17}{41}+\frac{-24}{41})$
$=\frac{14}{14}+\frac{-6}{17}+\frc{-7}{41}$

$=1-(\frac{6}{17}+\frac{7}{41})=1-\frac{365}{697}=\frac{332}{697}$

Bạn nên gõ đề bằng công thức toán (biểu tượng $\sum$ góc trái khung soạn thảo) để mọi người hiểu đề của bạn hơn nhé.

Theo Co-si, ta có: 

\(a^3+b^3+c^3>=3\sqrt[3]{a^3\cdot b^3\cdot c^3}=3bac\)

Dấu '=' xảy ra khi a=b=c

\(a^2=2\left(b+c\right)\)

=>\(a^2=2\left(a+a\right)=4a\)

=>\(a^2-4a=0\)

=>a(a-4)=0

=>\(\left[{}\begin{matrix}a=0\left(loại\right)\\a=4\left(nhận\right)\end{matrix}\right.\)

Do đó: a=b=c=4

\(T=4^3+4^{2023}+4=68+4^{2023}\)

Hi Isabella,

My brother Jude and I are planning a pool party to celebrate our birthdays. It’s on 27 August and it starts at 1 p.m. We’re having it at my uncle and aunt’s house (they’re on holiday) – their address is 48 Birkdale Rd. Don’t forget to bring your swimsuit! Can you bring something to drink, e.g., a bottle of Coke or Sprite? Hope you can come. Please reply by Friday.

Best wishes, Connor
