Answer 2

Answer 3

\(\dfrac{3737.43-4343.37}{2+4+6+...+100}\) 

Gọi \(A=2+4+6+...+100\) 

Số số hạng: \(\left(100-2\right):2+1=50\) 

Tổng dạy: \(\left(2+100\right).50:2=2550\) 

Gọi \(B=3737.43-4343.37\) 

\(B=101.37.43-101.43.37=0\) 

\(\Rightarrow\dfrac{3737.43-4343.37}{2+4+6+...+100}=\dfrac{0}{2550}=0\)
