Ответ:

x = 1

Пошаговое объяснение:

(3x - 1)³ = 8

(3x - 1)³ = 2³

3x - 1 = 2

3x = 2 + 1

3x = 3

x = 3 : 3

x = 1

I would like to tell you what happened to my uncle Oscar, or I would rather try to understand it and explain it to you. My uncle Oscar was a very nice man. Every morning on Monday, Tuesday, Wednesday, Thursday, and Friday he usually took the seven-forty-five (7.45) bus and started for work. He went to the bank early in the morning as he was an accountant (and by the way, a very good  one). He worked hard all day long and returned home rather late. My uncle was  forty-seven years old, married and had two children. His wife’s name was Agatha. Aunt Agatha was fond of talking and always talked too much and in a very loud voice. That’s why I think Uncle Oscar sel-dom had much to say. Their two children, Elizabeth and Julian, were not very pleasant. Both of them were large and loud like their mother. And they were selfish and greedy too. They didn’t think about their father much. He was a lit-tle quiet man, who spoke little and went about unnoticed. He liked music but didn’t play any musical instrument. He practically never went to the theatre or to the cinema and he didn’t visit exhibitions or museums either. Uncle Oscar didn’t go in for sports. You could never see him in the sitting room in front of the television watching sports programmes.  Uncle Oscar never complained about his boring life. I knew he had a hobby. He had a very good collection of stamps and he was happy only when he worked on his stamp collection. His children took no interest in their father’s hobby. But I, his nephew, did. Uncle Oscar showed me some stamps and ex-plained that they were really very expensive. Then on the 14th of October 1971 Uncle Oscar got up as usual at six-forty-five, made his own breakfast (Aunt Agatha, Elizabeth and Julian were still in bed; they never got up before 8), left the house and went to the bust stop. Some people who were at the bus stop that day didn’t see him at all. The others were not so sure. They couldn’t say anything definite. But that was the kind of per-son Uncle Oscar was: other people seldom noticed him. One thing was certain, he never got to the bank that morning.
