A=1+2+4+8+16+....+4096+8192

Nhìn vào biểu thức tính nhanh này ta thấy:

1+2+4=7 và số liền sau nó là 8

1+2+4+8=15 và số liền sau nó là 16

1+2+4+8+16=31 và số liền sau nó là 32

theo qui luật đó ta thấy tổng của các chữ số đứng trước nó sẽ bằng số liền trước nó

vậy 1+2+4+8+16+....+4096+8192 sẽ bằng 8191+8192

vậy biểu thức A có giá trị là:

8191+8192=16383

vậy A là: 16383

Do d' là ảnh của d qua phép tịnh tiến nên d' cùng phương d

\(\Rightarrow\) Phương trình d' có dạng: \(2x-3y+c=0\)

Gọi \(A\left(0;1\right)\) là 1 điểm thuộc d

\(T_{\overrightarrow{v}}\left(A\right)=A'\Rightarrow\left\{{}\begin{matrix}x'=0+1=1\\y'=1+\left(-2\right)=-1\end{matrix}\right.\) \(\Rightarrow A'\left(1;-1\right)\)

Thay tọa độ A' vào pt d':

\(2.1-3.\left(-1\right)+c=0\Rightarrow c=-5\)

Hay pt d' có dạng: \(2x-3y-5=0\)
