So the members of the meal are closely related and dependent on each other. This is different from the West, because everyone has their own ration, people are completely independent of each other. And the Vietnamese are the opposite, so they love chatting with their dinners, as opposed to Westerners avoiding talking when they eat. Chatting while eating is a necessity for the Vietnamese people, because the meal serves to "eat well", but also the opportunity for brothers, relatives and friends to gather to inquire health, Live together, share experiences and be comfortable discussing their favorite subject. Because there are delicious food that is not good weather, not good weather, without good food is not good, there is no place to eat delicious friends do not eat, not eat well, have friends mind The air of unhealthy meals is not good. Eat the pot, sit in the direction of: because everyone is interdependent, so consider the sitting and the size when eating. This is a high expression in the community life of the Vietnamese. It requires people not to eat too fast, too slow; Do not eat too much but do not eat too little; Do not eat or eat. Therefore, the phenomenon after eating, in the plate food is always left over food, and food in the cup of people have all eaten. This habit of eating reflects on the meal, a guest must eat deliciously to show gratitude and respect the landlord, but on the other hand to leave a few on the plate to prove that you are not. Starve, not glutton On the other hand, fast food indicates that people are in a hurry, rude, slow to eat, people have to wait, eat more, eat up greed, eat less, eat less is not good ... Folk stories often criticize people Accidentally eating and having many meals to eat. Therefore, our grandparents paid great attention and experimented in teaching their children: "Studying, learning to speak, learning package, learning open". In it, educating the way of eating is a top priority because through the way people eat, one can more or less comment and conclude on that individual's personality and their whole family. Must have a cup of fish sauce (or soy sauce) when eating. In the meal structure of the Vietnamese, while other dishes are eaten, people do not, and rice and fish sauce are all used, also dots. Therefore, the cup of tattoo has become a measure of attention, measuring the level of human culture. The fish sauce must be neat, clean, no noise, dots is to show people clumsy, descriptive, dot fish sauce that to fall into the fish sauce is unsanitary dish, dirty, dirty Missing (two, three times a dot) are people who do not work, or flaws, should not be trusted .. Do not eat too much or too little rice in each cup. The owner of the pot is very delicate and the size of the rice cooker for guests. Too many are easy to fall, scrape, (make guests clumsy) and there is no place for food; It is too little to eat quickly, have to bring several times (making guests bring food). See the rice in the pot is about to end, must reduce the speed of their own and family (by little), avoid leaving the chopsticks in the pot, to make guests feel full, most comfortable. Use chopsticks when eating: This is the popular way of eating in Asia. It is a unique way to simulate the movement of a bird to pick up seeds, resulting from the habit of eating things that can not be handled or handled (such as rice, fish, fish sauce ...) of the East. South Asia. Westerners, meanwhile, have to use a set of knives, spoon, and dishes (simulating the tearing of animals), each performing a single function (product of analytical thinking). Vietnamese chopsticks perform in a comprehensive and flexible manner a variety of functions: picking and tearing, girdling, crossing, mixing, dipping, and connecting their long arms to get food far away!on in other countries.

Độ rượu\(=\dfrac{V_{rượu}.100}{V_{ddrượu}}\) \(\Rightarrow\)\(V_{rượu}=\dfrac{độrượu.V_{rượu}}{100}\)=\(\dfrac{92.1}{100}\)=0,92 (l)

\(D=\dfrac{m}{V}\Rightarrow m=D.V\)=0,8 . 0,92 = 0,736 (g)

Câu trả lời:

2P = 24.(5^2 + 1 )( 5^4 + 1 ) (5^8 +  1 )(5^16 + 1 )

2P = ( 5^2 - 1 )((5^2  + 1 )( 5^4 + 1 ) (5^ 8 + 1 )( 5^ 16 + 1)

2P = ( 5 ^ 4 - 1 )( 5 ^ 4 + 1 ) (5^8 + 1 )(5^16 + 1 )

2P = ( 5 ^8 - 1 )( 5^8 + 1 )( 5^16 + 1)

2P = ( 5 ^16 - 1 )( 5^16 + 1 )

2P = 5^32 - 1 

=> P = \(\frac{5^{32}-1}{2}\)
