Question

[Nguyễn Văn Duyệt]

\(T=\frac{3}{4}\times\frac{8}{9}\times\frac{15}{16}\times...\times\frac{575}{576}\times\frac{624}{625}\)

Answer 1

[Hồ Thu Giang]

T = \(\frac{3}{4}.\frac{8}{9}.\frac{15}{16}....\frac{624}{625}\)

T = \(\frac{1.3.2.4.3.5.....24.26}{2.2.3.3.4.4.....25.25}\)

T = \(\frac{\left(1.2.3.....24\right)\left(3.4.5.....26\right)}{\left(2.3.4.....25\right)\left(2.3.4.....25\right)}\)

T = \(\frac{26}{25.2}\)

T = \(\frac{13}{25}\)
