Bằng -16322,21709

198 + x và 270 - x đều chia hết cho x

Mà x chia hết cho x nên 198 : 270 chia hết cho x

= > x = ƯCLN (198 ; 270)

198 = 2.3².11 ; 270 = 2.3³.5  

= > ƯCLN (198 ; 270) = 2.3² = 2.9 = 18

Vậy x = 18.

Vietnam have a lot of natural beauty. Ha Long Bay is located in northeast Vietnam, is part of the west coast  Bac Bo bay. My feeling about Ha Long Bay was first to see firsthand the magical beauty that nature has bestowed to Vietnam is similar to what I learned about through books and television: Ha Long bay is really beautiful and sexy.  Ha Long Bay as a huge picture wearing extremely lively. That's the beautiful art works, the flowers of creation, of nature turn thousands of islands senseless silence became quite sculpture, painting with all our perfect appearance, charm, just very familiar just as alien to human beings. Thousands of islands bobbing on the waves of shimmering, majes both strong but also very soft and graceful, lively. Ha Long bay is beautiful, but would be nicer, more roman if colored by the sentiments of respect and love for visitors to the bay. You and I, we have the owner just as tourists, we get together to preserve the precious gift that nature has bestowed favor for the country of Vietnam. Ha Long bay is the wonder in the world. Ha Long bay-my love.

I was born and grown up on the poor land in Duc Tho district, Ha Tinh province. That’s where deeply attaches to me 24 years of life. If anyone who asks me that “What’s the thing your most proud of?” .I will answer that’s my hometown. Duc Tho is the land poor where the people live by rice cultivation, breeding, and fishing. Although the life is very difficult, but the people is very friendly, and studious. In Duc Tho, there is a Tung Anh village where called “Doctor village”. Duc Tho is also the home of Tran Phu Secretary General, and marked many memories of the great leader Ho Chi Minh.

If you come to Duc Tho, you will feel many interesting things, visiting Tran Phu tombstone, La Giang dyke, rowing on La driver, and enjoying the traditional songs. In the evening, they can enjoy a special food which is “mussel rice” – just only eat one time, you will never forget.

Beautiful and unobtrusive! Duc Tho always tries to grow, and to improve the life of people, but keeping the traditional culture.

Kể về một nơi trên Việt Nam:

In VietNam has a lot of attractions. But my favourite place in Viet Nam is Hoi An. It's in Da Nang City. It's a historic city. In there we can eat "banh quang" and lighting lanterns in the evening. Also we can play many games and enjoy cuisine in there. That's about Hoi An.

Kể về nơi mình sống:

I'm living in the capital city in VietNam. It's Ha Noi. Ha Noi is big and lots of theatre. Ha Noi has temples : Mot Cot's temple, ........ You must try ice cream in Trang Tien. It's delicious and famous. You must try it. That's about Ha Noi.

b,ta có 51 có chữ số tận cùng là 1 nên51^47 có chữ số tận cung là 1

ta lại có :47^102=(47^3)^34=(...1)^34 có chữ số tận cùng là 1

nên 51^47+47^102 có chữ số tận cùng là :1+1=2

vậy ..............

câu c tương tự ,bạn đưa vệ các số có tận cùng là (0;1;5;6) là có thể tìm được tạn cùng nhé

các bạn có thể làm bài này theo mod hộ mình nhé

abc = 37 . ( a + b + c )

abc gấp 37 lần ( a + b + c )

TH1:

a = 1 ; b = 1 ; c = 1

\(\Rightarrow\)111 = 37 . ( 1 + 1 + 1 )

         111 = 37 . 3 ( chọn )

TH2:

a = 1 ; b = 2 ; c = 3

\(\Rightarrow\)123 = 37 . ( 1 + 2 + 3 )

          123 = 37 . 6 ( loại )

Vậy abc = 111

abc=37x(a+b+c)

abc gấp 37 lần (a+b+c)

TH1:

a=1;b=1;c=1

SUy ra 111=37.(1+1+1)

111=37.3(chọn)
