Второй разделить на 2 логарифма типа будет так:
-log 7 (корень из 7 / 49) = -(log7(корень из 7) - log7(корень из 49)) = -(1/2 - 1)=1/2

Task 1. Read the text below and complete the task.

Summer Holidays

People like to travel during their summer holidays. Some people go abroad to see new countries, some people prefer to go to the country-side to enjoy country-life far from noise and fuss of big cities.

Some people like to spend their holidays in cities, visiting theatres, museums and going sightseeing. But a great number of people go to the seaside in summer.

I like to have rest at the seaside best of all. My family and I always have our holiday on the coast. Sea and sunshine that is what we look forward to every summer. Hotels at the large seaside towns are rather expensive, so we usually go to a holiday camp.

Last year we spent our holidays in such a camp. Each day was full of small joys. We swam in the sea, lay in the sun, played different games and had a wonderful time. We lived there for about a month and did not even notice when the time came for us to return home. The time flew very quickly. It was a wonderful rest.
