Bài 9:
a: \(2^{195}=8^{65}\)
\(3^{130}=9^{65}\)
mà 8<9
nên \(2^{195}< 3^{130}\)
56083 | 123
688 | 455
733 |
118
=> \(56083:123=455\left(dư.118\right)\)
Câu 1: C
Câu 2: D
Câu 3: B
Câu 4; B
Câu 5: D
Câu 6: C
Câu 7: A
Câu 8: A
\(2.16\ge2^n>4\)
\(2.2^4\ge2^n>2^2\)
\(2^5\ge2^n>2^2\)
=> \(n\in\left\{3,4,5\right\}\)
Vậy: \(n\in\left\{3,4,5\right\}\)
Bội của 4 từ 32 đến 250 là: 32; 36; 40; ...; 250
Số bội của 4 từ 32 đến 250 là: ( 250 - 32 ) : 4 + 1 = 56
