Автор ответа: Shelkovaia

$sqrt{90} + sqrt{10} =3 sqrt{10} + sqrt{10} =4 sqrt{10}$

Автор ответа: Eeeeeeboy

Выводим часть корня из $В sqrt{90}$ получается
$sqrt{9*10}$ Теперь можно вывести 9 за корень получается
3 $sqrt{10}$
Теперь так как корни равные складываем
3 $sqrt{10}+ 1sqrt{10}$ =4 $sqrt{10}$

your ideas to Exercise 1. FUNCTIONAL ZONES Functional zones in a city are the areas where people go to do particular things. There are three main functional areas in a modern city: the CBD (central business district), the industrial zone and the residential zone. The CBD is often called the city centre. It is usually in the historic centre of a city. It has most of the shops and services, like banks, libraries, and also offices and the town hall. There are also places for entertainment like theatres, cinemas and swimming pools. Land is expensive in the CBD so there are often a lot of tall buildings like skyscrapers. Some historic cities don't have these more modern buildings because they want the city to look traditional. The industrial zone is where the factories, warehouses and industries are. Many years ago, these zones were in the centre of cities, but they moved out, probably because of the noise and pollution. This area is usually less attractive than the central areas. Workers often travel here from where they live, so these zones usually have good transport links for trains and cars to move people, materials and products to and from the factories Residential zones are often on the outside of a city The buildings are newer and the land is cheaper here so this is where people, especially families, live. There are schools and more open spaces like parks, and there is less traffic and pollution than in other zones.
