\(A=1+2+2^2+2^3+...+2^{33}\\ \Rightarrow2A=2+2^2+2^3+2^4+...+2^{34}\\ \Rightarrow2A-A=\left(2+2^2+2^3+2^4+...+2^{34}\right)-\left(1+2+2^2+2^3+...+2^{33}\right)\\ \Rightarrow A=2^{34}-1\)
Ta có: \(2^{34}=2^{17.2}=\left(2^{17}\right)^2\) là số chính phương
Do đó: \(A=2^{34}-1\) không phải là số chính phương
Vậy...

Thanks 🙂

M không nằm giữa N,P

N không nằm giữa M và P

Do đó: P nằm giữa M và N

\(1200-2^3+10^3\)

Tích của số chia và thương là 86-9=77

\(77=7\cdot11=11\cdot7=1\cdot77=77\cdot1\)

=>Số chia và thương có thể là các cặp số là (7;11);(11;7);(1;77);(77;1)

86:7=12 dư 2

=>Loại

86:11=7 dư 9(nhận)

86:1=86(Loại)

86:77=1 dư 9(nhận)

Vậy; Số chia và thương có thể là (11;9);(77;1)
