Câu 1. So sánh: a, 2300 và 3200 b, 202303 và 303202
c, 199010 + 1990 9 và 199110
a, Ta có:
2300 = (23)100 = 8100
3200 = (32)100 = 9100
Vì 8100 < 9100 nên 2300 < 3200
b, Ta có:
202303 = (2023)101 = 8242408101
303202 = (3032)101 = 91809101
Vì 8242408101 > 91809101 nên 202303 > 303202
c, Ta có:
199010 + 19909 = 19909(1990 + 1) = 19909.1991
Vì 19909.1991 < 199110 nên 199010 + 19909 < 199110
