\(I=\frac{1}{6.10}+\frac{1}{10.14}+...+\frac{1}{402.406}\)

\(\Leftrightarrow I=\frac{1}{4}\left(\frac{1}{6}-\frac{1}{10}+\frac{1}{10}-\frac{1}{14}+...+\frac{1}{402}-\frac{1}{406}\right)\)

\(\Leftrightarrow I=\frac{1}{4}\left(\frac{1}{6}-\frac{1}{406}\right)\)

\(\Leftrightarrow I=\frac{1}{4}\cdot\frac{100}{609}\)

\(\Leftrightarrow I=\frac{25}{609}\)

4I = 4/6.10 + 4/10.14 + ......+ 4/402.406   À mình nói thêm tử số sẽ dựa vào khoảng cách giữa 2 mẫu số

    = 1/6 -1/10 + 1/10 -1/14+......+1/402 -1/406

    = 1/6 - 1/406 = 100/609

I   =100/609 : 4 = 25/609

25.4+19190

=(25.4)+19190

=100+19190

=19290

26 tháng 12 2016

25 • 4 +19190

= 100 + 19190

= 19290

   25 . 6 + 25 . 4 + 25 . 18 + 25 . 12 

= 25 . (6 + 4 + 18 + 12)

= 25 . 40

= 1000

6 tháng 6 2017

25 x 6 + 25 x 4 + 25 x 18 + 25 x 12

= 25 x ( 6 + 4 + 18 + 12 )

= 25 x 40

= 1 000
