Còn lại đúng hết rồi nhé

=420 :[214 -4]=420 : 210=2

2

c, 420 : [ 214 - (18 - 16)² ]

= 420 : [ 214 - 2² ]

= 420 : [ 214 - 4 ]

= 420 : 210

= 2

Lời giải:
Giả sử có $a$ người đi tiêm vacxin. Theo bài ra thì $a\vdots 12, 10, 15$

$\Rightarrow a\vdots BCNN(12,10,15)$

$\Rightarrow a\vdots 60$

$\Rightarrow a\in\left\{0; 60; 120; 180; ....\right\}$

Vì $a$ nằm trong khoảng từ $100$ đến $130$ nên $a=120$ (người)

Lời giải:

\(H=2-\frac{3}{17}-\frac{5}{23}+\frac{2}{17}-\frac{1}{2023}-\frac{16}{17}-\frac{18}{23}\\ =2-(\frac{3}{17}-\frac{2}{17}+\frac{16}{17})-(\frac{5}{23}+\frac{18}{23})-\frac{1}{2023}\\ =2-1-1-\frac{1}{2023}=-\frac{1}{2023}\)

---------------------

\(K=\frac{7}{23}.\frac{-11}{17}+\frac{7}{23}.\frac{4}{17}-\frac{7}{23}.\frac{10}{17}\\ =\frac{7}{23}(\frac{-11}{17}+\frac{4}{17}-\frac{10}{17})\\ =\frac{7}{23}.\frac{-17}{17}=\frac{-7}{23}\)
