so sanh
A=1+5+5^2+....++5^9 / 1+5+5^2+...+3^8 va B=1+3+3^2+...+3^9 / 1+3+3^2+...+3^8
so sanh A va B biet A=1+5+5^2+5^3+...+5^9/1+5+5^2+5^3+...+5^8 va B=1+3+3^2+3^3+...+3^9/1+3+3^2+3^3+...+3^8
so sánh
A=\(\frac{5^0+5^1+...+5^9}{5^0+5^1+...+5^8}\)
B=\(\frac{3^0+3^1+..+3^9}{3^0+3^1+...+3^8}\)
cho A:1+5+5^2+.....+5^9/1+5+5^2+.........+5^8
