Объяснение:

{7}^{30} \times {2}^{30} - ( {14}^{15} - 1)( {14}^{15} + 1) = {14}^{30} - ( {14}^{15} - 1) \times ( {14}^{15} + 1) = {14}^{30} - ( {14}^{30} - 1) = {14}^{30} - {14}^{30} + 1 = 1

Sandwich generation
There are different families in terms of size and number of generations. There are so-called nuclear families, which consist of parents and dependent children, that is, children who are not old enough to take care of themselves in financial terms. There are also extended families, which also include grandmothers and grandfathers, sometimes even aunts and uncles with their spouses (spouse — супруг, супруга) and kids. They all live together and form one household.
In the past, most families in Russia and other countries were extended families, and three or more generations used to live together. (1) The first refers, mainly, to the young generation — when young people become independent financially and are able to support themselves, they usually leave their parents’ house. The latter is about elderly people — grandparents often want their own personal space too and live apart from their grown-up children as long as they are able to take care of themselves.
However, a new trend of the contemporary society has been spotted recently by western researchers. Statistics say that more and more people turn back to extended family lifestyle, when several generations live in one household. Young people tend to stay with their parents even when they become adult. Grandparents, who live longer than they used to, also prefer to share a flat or a house with their children and grandchildren, as they need support and company of other members of the family. But the main reason for that is, certainly, money. (2). It saves money and makes life easier as the household chores (домашние обязанности) can be distributed among several members of the family according to their likes and abilities.
Along with those indisputable advantages there are some disadvantages — different generations have different values, habits and interests, they often get on each other’s nerves, which leads to conflicts. (3). A new term “the sandwich generation” has appeared to denote these people. The sandwich generation are those who take care of the elderly and the young, and rule the family in general. (4).Life is quite tough to her. To survive and to maintain a happy family she needs to exercise the extreme tolerance when looking after both children and parents. It would be nice of the other members of the family to appreciate it.
- There should be someone who is able to resolve conflicts, bridge different interests and take care of others.
- Lots of people prefer extended family because it gives them comfort and support.
- Nowadays the situation is different and many people prefer living on their own, if, of course, can afford it and if their health allows them to do it.
- In most cases this is the daughter of the elderly generation and    the mother of the young generation.
- It’s obvious that one big household is more economical than three little ones.
