1. So sánh:

Bài 1:
a) 3500 = 3100.5 = (35)100 = 243100
5300 = 5100.3 = (53)100 = 125100
Vì 243100 > 125100 nên 3500 > 5300
b) Không thể biết, nếu n > 100 thì thừa lớn hơn, nếu n < 9 thì thừa bé hơn.
\(\frac{1}{3}^{101}.....\frac{1}{2}^{145}\)
Đề có sai ko bạn?
Ta có \(x\inƯ\left(30\right)\)\(\left(ĐKXĐ:x\le8\right)\)
\(< =>x\in\left\{1;2;3;5;6;10;15;30\right\}\)
Do \(x\le8\)suy ra ta có bộ số x thỏa mãn sau :
\(x\in\left\{1;2;3;5;6\right\}\)
Cây sen, cây súng... di chuyển nhờ nước.
