\(1\frac{1}{5}\)X \(1\frac{1}{6}\) X \(1\frac{1}{7}\) X \(...\)X \(1\frac{1}{2014}\) = x

x = \(\frac{6}{5}\) X \(\frac{7}{6}\) X \(\frac{8}{7}\) X \(...\)X \(\frac{2015}{2014}\)

x = \(\frac{6\cdot7\cdot8\cdot...\cdot2015}{5\cdot6\cdot7\cdot...2014}\)

x = \(\frac{2015}{5}\)

x = 403

6/5 × 7/6 × 8/7 × ... × 2015/2014 = x

2015/5 = x

x = 403

Vậy x = 403

Ủng hộ mk nha ♡_♥☆_★^_-

\(\Rightarrow x=\frac{6}{5}\times\frac{7}{6}\times\frac{8}{7}\times.......\times\frac{2015}{2014}\)

\(\Rightarrow x=\frac{6\times7\times8\times......\times2015}{5\times6\times7\times......\times2014}\)

\(\Rightarrow x=\frac{2015}{5}=403\)

chỗ \(\frac{2014}{5}sai\Rightarrow\frac{2015}{5}=403\)

bạn cứ nhân ra là xong

\(X=\frac{6}{5}x\frac{7}{6}x\frac{8}{7}x....x\frac{2014}{2013}=\frac{2014}{5}\)

tìm số tự nhiên mà

4

nhớ tick nha

\(1\frac{1}{5}\times1\frac{1}{6}\times.......\times1\frac{1}{2014}=x\)

\(\frac{6}{5}.\frac{7}{6}.........\frac{2015}{2014}=x\)

\(\frac{2015}{5}=x\)

\(x=403\)

\(1\frac{1}{5}.1\frac{1}{6}.1\frac{1}{7}...1\frac{1}{2014}=x\)

\(\frac{6}{5}.\frac{7}{6}.\frac{8}{7}...\frac{2015}{2014}=x\)

\(\frac{2015}{5}=x\)

\(x=403\)

Vậy x = 403

Ủng hộ mk nha ^_^

x=403

\(\frac{6}{5}x\frac{7}{6}x\frac{8}{7}x...x\frac{2015}{2014}=\frac{2015}{5}=403=>X=403\)

X=430

k cho c nhe!

X=\(\frac{6}{5}.\frac{7}{6}....\frac{2015}{2014}\)

   =\(\frac{2015}{5}\)

  =403

 6/5x7/6x...x2015/2014

=1/10020

X=403 nhé

1 1/5=6/5 ,,1 1/6=7/6........

ta có:X=6/5+7/6+.....+2015/2014.

dùng phương pháp "khử liên tiếp"ta có:........từ đó ra

vẫn như thế.dùng phương pháp khử liên tiếp ta có:

  6/5+7/6+.......+2015/2014

=đang duyệt...........!!!!!!!!!!!!!

\(=\frac{6}{5}.\frac{7}{6}.\frac{8}{7}............\frac{2015}{2014}=\frac{2015}{5}=403\)

=> \(\frac{6}{5}.\frac{7}{6}.\frac{8}{7}...\frac{2014}{2013}.\frac{2015}{2014}=x\)

=> \(\frac{6.7.8.9...2014.2015}{5.6.7.8...2013.2014}=x\)

=> \(x=\frac{2015}{5}=403\)
