Автор ответа: LFP

чтобы сравнить два числа, нужно оценить их разность:

если a-b > 0 ---> a > b

если a-b < 0 ---> a < b

3√2+√20 - (√32+2√5) = 3√2+2√5 - 4√2-2√5 = 3√2 - 4√2 = -√2 это отрицательное число -√2 < 0, следовательно, 3√2+√20 < √32+2√5

WEEKEND ARTS REVIEW: FILMS

A The Class

The Class is about a young teacher who works at a school in a poor area of Paris and his difficult students. The story was originally a book written by Frangois Begaudeau. The film tells the sad story of how a teacher tries to teach his class of teenage students but fails, because the students don’t respect education or teachers, and because they have no desire to learn. Everyone who stars in the film (including Begaudeau, who plays himself) is a non-professional. People expect The Class to be boring because the teacher-student theme has appeared in films many times before, but it isn’t. It is an absolutely brilliant film and no one should miss it.

B Slumdog Millionaire

Director Danny Boyle’s Slumdog Millionaire is the story of Jamal, a poor boy in India, who goes on the TV show ‘Who wants to be a millionaire?’. The story was originally a prize-winning novel by Indian author Vikas Swarup. Jamal wins the TV show. But before he does, they take him to a police station because the police think that he is cheating. While the police ask Jamal questions, we see events from Jamal’s life which explain why he knows the answers.

At one point, the creators of Slumdog Millionaire had decided not to show it in film theatres, and just make it into a DVD. Luckily, they changed their minds, because this film is now an international hit!

C American Teen

American Teen is a documentary film by director Nanette Burstein. Burnstein filmed the lives of five teenagers, who go to a school in Indiana, USA. She followed the students filming their everyday lives for a year, because she wanted to show what it is like to be a teenager in America today.

American Teen is an enjoyable documentary, but sometimes it doesn't feel true to life. In fact, some film critics think that Burstein gave the teens lines to learn. But in interviews, the teenagers have always said that the film is 100% real-life and no one is acting.

Whether real-life or not, American Teen is an entertaining look at young people today.
