(161616\212121+2022\3033)*7
=(\(\frac{161616}{212121}+\frac{2022}{3033}\))*7
=(\(\frac{16}{21}+\frac{2}{3}\))*7
=\(\frac{30}{21}\)*7
=\(\frac{210}{21}\)
=10

tick đó nha
My hometown is Quang Yen. It is in the west of Quang Ninh Province. It is an ancient land. It is famous for historical sites, festival , Phong Coc communal house, Tien Cong temple, Bach Dang river and 2 Gieng Rung ironwood trees. The weather is hot and dry, I like my hometown very much.

`2^2 .2^3-(2022^0+19):2^2`
`=4.8-(1+19):4`
`=4.8-20:4`
`=32-5`
`=27`
\(2^2\cdot2^3-\left(2022^0+19\right):2^2=4\cdot8-\left(1+19\right):4=32-20:4=32-5=27\)
\(\left(\frac{161616}{212121}+\frac{2022}{3033}\right)\times7=\left(\frac{16.10101}{21.10101}+\frac{1011.2}{1011.3}\right)\times7=\left(\frac{16}{21}+\frac{2}{3}\right)\times7\)
\(=\frac{10}{7}\times7=10\)
Bài làm
\(\left(\frac{161616}{212121}+\frac{2022}{3033}\right)x7\)
= \(\left(\frac{16}{21}+\frac{2}{3}\right)x7\)
= \(\left(\frac{16}{21}+\frac{14}{21}\right)x7\)
= \(\frac{30}{21}x7\)
= \(\frac{30}{3}\)
= \(10\)
