Tờ vé số có dạng \(\overline{a_1a_2a_3a_4a_5a_6}\in A=\left\{0;1;2;3;4;5;6;7;8;9\right\}\)
\(;a_i\ne a_j\)
Chọn \(a_1\ne0\) nên \(a_1\) có 9 cách chọn.
5 số còn lại là chỉnh hợp chập 5 của 8 số còn lại \(\in A\backslash\left\{a_1\right\}\)
\(\Rightarrow\)Có \(A_8^5\) cách.
Vậy có tất cả \(A_8^5\cdot9=60480\) vé số.
- Hợp chất vô cơ: CO2, Na2CO3
- Hợp chất hữu cơ:
+ Hiđrocacbon: C4H10, C6H6, C3H4
+ Dẫn xuất của hiđrocacbon: C3H8O, CH3Cl, C6H6Cl6
đặt \(A=2+2^2+2^3+...+2^{2018}\)
\(\Rightarrow2A=2^2+2^3+2^4+...+2^{2019}\)
\(\Rightarrow2A-A=2^{2019}-2\)
\(\Rightarrow A=2^{2019}-2\)
