Ответ:

x = 32, x = 1/2

Пошаговое объяснение:

$t = log_{2}x => t^{2} - 4t - 5 = 0 => t = 5, t_{2} = -1 => log_{2}x = 5 => x= 32; log_2{x} = -1 => x=\frac{1}{2}$

Текст:
Mark Twain, the famous American writer, was well-known as a lecturer. Literary clubs often invited him to speak. Before one of his lectures a club member came to him and said:

"Twain, people say that you can tell very funny stories. I hope that during your lecture you will tell a story that will make my uncle laugh. He hasn't laughed for ten years."

"I'll do my best." Mark Twain said.

When he began his lecture, Mark Twain noticed the club member. He was sitting in front of him with an old man who had a very sad face.

Mark Twain began to tell jokes, one after another. "I told long jokes and short jokes, new jokes and old jokes," Mark Twain told his friends. "I told every joke I knew and soon everybody was laughing. Everybody but not the old man. He was looking at me with cold, blue eyes. I couldn't make him laugh, and I tried again and again. But nothing helped..."

After the lecture, the club member came to Mark Twain and said, "Thank you, Mr. Twain. I have never heard so many funny stories."

"They weren't funny enough for your uncle," Mark Twain answered. "He

didn't even smile."

"I know", the man said. "He hasn't laughed for ten years. But I didn't tell you that he hadn't heard anything for ten years. He is deaf."
