Пусть 5^y=a, 2^y=b
{b+10a=25
{12b-4a=52 |:4 ⇒ 3b-a=13

{b=25-10a
{3(25-10a)-a=13
-30a+75-a-13=0
31a=62
a=2
b=5
Возвращаемся к замене
{5^[y]=2 ⇒ {y=log5(2)
{2^[x] = 5 ⇒ {x=log2(5)

Ответ: (log2(5));log5(2))

Reading 1 Read the texts about sleep problems. Match the sentences (1–6) with the people (A–C). You can choose the people more than once. Which person: 1 has ignored his/her doctor’s advice? ……………………. 2 has a problem which few people know about? …………………….. 3 has trouble getting to sleep? …………………….. 4 has had to change his/her life because of the problem? ……………… 5 says his/her problem is more serious than people think? ......................... 6 is getting help for his/her problem? …………………. A. Tony My sleep problem is really quite serious, but a lot of people think that it’s normal and even funny. I snore at night when I’m asleep – and my wife says that it’s pretty loud! Now, I know snoring isn’t unusual and there is a lot of advice on how to stop someone snoring, but my snoring is different! It’s linked to something called sleep apnoea. When you snore it means that you can’t keep your throat open when you’re asleep. In my case, I actually stop breathing for ten seconds or more. It worries my wife but I always wake up afterwards! B. Lizzie My problem is very unusual and most people have never heard of it. It’s called narcolepsy and it has changed my whole life. Narcolepsy is when people fall asleep anywhere at any time and they can’t stop it. Since the problem started I’ve had to stop working because you can’t do a good job if you fall asleep in the middle of a conversation! My friends have been very supportive but I don't like going out now because I get embarrassed about it and also I’ve had to stop driving as it’s much too dangerous. I go to a special sleep clinic now and they’re helping me a lot. C. Robert I’ve had this sleep problem since I was a child and I know a lot of people who have the same problem. It’s called insomnia and it means I sleep very badly. Sometimes I can’t get to sleep for hours and sometimes I go to sleep OK, but I wake up in the middle of the night and then I can’t get back to
