=(sqrt(3)/12)(a-b)(a^2+b^2+ab)=(sqrt(3)/12)(a^3-b^3)

Помогите составить 5 вопросов по этому тексту на английском.

Supercomputers are the most powerful computers in terms of

processing. They are useful for problems requiring complex calculations.

Because of their size and expense, supercomputers are relatively rare.

They are typically used by large organizations such as universities,

government agencies, and very large businesses.

Mainframe computers, which generally have many terminals or PCs

connected to them, handle massive amounts of input, output, and storage.

Mainframe computers are commonly used in corporations and government

agencies, but they are also used as e-commerce servers, handling

transactions over the Internet.

Minicomputers are smaller than mainframes but larger than

microcomputers. They usually have multiple terminals. Minicomputers

are used more and more often as network servers and Internet servers.

Workstations are powerful single-user computers that are used by

engineers, scientists, and graphic artists. Like minicomputers, workstations

are often used as network and Internet servers.Microcomputers are more commonly known as personal computers.

The term PC often denotes microcomputers that are either IBM-PCs or

compatibles. The term can also refer to personal computers made by

other manufacturers, such as Apple. Desktop computers are the most

common type of personal computer. Notebook computers (laptops) are

used by people who need portable computing power outside the office or

away from home. Handheld personal computers are the smallest computing

devices. They lack the power of a desktop or notebook PC, but they offer

specialized features for users who need only limited functions and small size.
