bạn tự giải ra nhé!mk làm tắt thui

Đó là bánh chưng

nếu tính theo bài này thì kq sẽ là 4 vì

4+2+3=5 mà phép tính sau ta phân tích được:

4x2+2x2+3x2=5x2

=>3+2+1=2

3x2+2x2+1x2=2x2=4

chắc chắn

C= \(\frac{1}{2}.\left(\frac{2}{2.4}+\frac{2}{4.6}+\frac{2}{6.8}+....+\frac{2}{98.100}\right)\)

  = \(\frac{1}{2}.\left(\frac{1}{2}-\frac{1}{4}+\frac{1}{4}-\frac{1}{6}+....+\frac{1}{98}-\frac{1}{100}\right)\)

  = \(\frac{1}{2}.\left(\frac{1}{2}-\frac{1}{100}\right)\)

  = \(\frac{1}{2}.\left(\frac{50}{100}-\frac{1}{100}\right)\)

  = \(\frac{1}{2}.\frac{49}{100}\)

  = \(\frac{49}{200}\)
