24^2-(0,24)^2 24.24 = (24-0.24)(24+0.24)(по формуле разность квадратов)  24.24 = 23.76*24.24 24.24 = 23.76 (сокращаем и в числителе и в знаменателе)
вот и все)

Task 1 Read the text. Mark the sentences TRUE or FALSE according to the context.
My dream job
When I was younger, it was so easy to choose my future profession. At the age of 5 I wanted to be a shop-assistant in a candy store, at the age of 10 I was sure that I would become a doctor. Now I am little bit confused.
Well I passed few tests and realized that I can be good for few professions. First of all I would like to say, that perfect profession for me is not only good salary and career, but also my satisfaction. I mean I can wake up every morning happy and full of energy to do my job. Also I would like to have good colleagues and loyal head. So I am good for few jobs: economist, secretary, interpreter, logistic or programmer.
For now I really would like to be an interpreter. My English is really good. I can study one more language at the university and I will be able to speak 3 languages. Another good thing about this profession is possibility to travel. I am really exciting about it. Traveling can give us chance to explore the world and to open new horizons. This is what I am looking for.
New colleagues and people can always teach you some new things. You can get great experience while communicating. And another good thing is working with international companies. Just imagine, you may have a possibility to work abroad with new technologies, to learn something new. It is also a possibility to get promotion.
The most important thing still is to be happy with your job. Then you can solve any problems and get the best results in your team.
