Trong 1 giờ, An làm được: \(\dfrac{1}{4}\)(công việc)

Trong 1 giờ, Bình làm được: \(\dfrac{1}{6}\)(công việc)

Sau 2 giờ hai người làm chung thì số phần công việc còn lại là:

\(1-2\times\left(\dfrac{1}{4}+\dfrac{1}{6}\right)=1-2\times\dfrac{5}{12}=1-\dfrac{5}{6}=\dfrac{1}{6}\)

Thời gian Bình hoàn thành phần công việc còn lại là:

\(\dfrac{1}{6}:\dfrac{1}{6}=1\left(giờ\right)\)

\(A=1+2+2^2+2^3+...+2^{33}\\ \Rightarrow2A=2+2^2+2^3+2^4+...+2^{34}\\ \Rightarrow2A-A=\left(2+2^2+2^3+2^4+...+2^{34}\right)-\left(1+2+2^2+2^3+...+2^{33}\right)\\ \Rightarrow A=2^{34}-1\)
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...
