\(2013=2.1000+10+3=2.10^3+1.10^1+3.10^0\)
\(20112013=2.10000000+100000+10000+2.1000+10+3\)
\(=2.10^7+10^5+10^4+2.10^3+10^1+3.10^0\)
2013 = 2 x 1000 + 10 + 3 = 2 x 10^3 + 1 . 10^1 + 3 . 10^0
20112013 = 2 x 10000000 + 100000 + 2 x 1000 + 10 + 3 = 2 x 10^7 + 10^5 + 10^4 + 2 x 10^3 + 10^1 + 3 x 10^0
ok nhé với lại 10^2 là 10 mũ 2 nhé =>

Nghĩ vậy,sai thì thông cảm ạ
bcdef = b.10000+c.1000+d.100+e.10+f.1
bcdef = b.10^4+c.10^3+d.10^2+e.10+f
sai thì xin lỗi
