if she have noney...

\(=1+\dfrac{1}{2}\cdot\dfrac{2\cdot3}{2}+\dfrac{1}{3}\cdot\dfrac{3\cdot4}{2}+...+\dfrac{1}{20}\cdot\dfrac{20\cdot21}{2}\)

\(=1+\dfrac{3}{2}+\dfrac{4}{2}+...+\dfrac{21}{2}\)

=(2+3+4+...+21)/2

=(20*23/2):2=230:2=115

\(2.16\ge2^n>4\)

\(2.2^4\ge2^n>2^2\)

\(2^5\ge2^n>2^2\)

=> \(n\in\left\{3,4,5\right\}\)

Vậy: \(n\in\left\{3,4,5\right\}\)

have been

have been

will be

Nếu dùng thì hiện tại hoàn thành:

have been => in four years - trong vòng 4 năm

Tùy theo ngữ cảnh mà khi in + khoảng thời gian thì ta có thể chia ở thì hiện tại, quá khứ hay tương lai; nhưng với câu này thì cô nghĩ will be hoặc have been đều được.
