Thanh Hoa is my hometown. It is a province located in the center of my country. 

I guess just like everyone else, I'm in love with this city's nature. It's a coastel city and my home is quite near the beach. Everyday, I can go to the seaside, enjoy the air and chat with my friends while having snacks.

Yes, definitely. My hometown is the best place to visit on a holiday as it has the best scenic views and a lot of places to roam around. Also, my hometown is kind of famous for its delicious food and shopping areas.

To be honest, I would say I like everything, but what I like the most may be its priviledge in natural landscapes. I mean my city is well - known for having incredible scenary everywhere from the beach to the east to green forest to the west.

In recent years, my city has really changed a lot and progressively developed day by day. Earlier, the roads were not properly constructed, so at that time, there were many misfortunes or road mishaps happening. But now, roads are reconstructed well in order to avoid such major accidents on the road.

a. Tính V khí H₂ thoát ra (đktc)

3x+17=12

3x     = 12-17

3x     = -5

x       = -5:3

x       = \(\frac{-5}{3}\)

nha!

x² = 20 - 11

x² = 9

x² = 3²

=> x = 3

x³ = 40 + 24

x³ = 64

x³ = 4³

=> x = 4

là số 5

a/ (1000 + 1) : 11 = 91 = 7 . 13

b/ 14² + 5² + 2² = 225 = 5² . 3²

c/ 29 . 31 + 144 : 12² = 900 = 2² . 3² . 5²

d/ 333 : 3 + 225 : 15² = 112 = 2⁴ . 7
