 Lê Mạnh Tiến Đạt giúp mk nhé

Answer 1

dat off roi

Answer 2

3/4x8/9x15/16x24/25x35/36=7/12

Answer 3

on lai roi

Answer 4

ai và kết bạn với mình thì mình cho 3

Answer 5

\(\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{9}\right)x\left(1-\frac{1}{16}\right)x\left(1-\frac{1}{25}\right)x\left(1-\frac{1}{36}\right)\)

\(=\)\(\frac{3}{4}\) x       \(\frac{8}{9}\)    x       \(\frac{15}{16}\)   x       \(\frac{24}{25}\)   x       \(\frac{35}{36}\)

\(=\frac{7}{12}\)

Answer 6

( 1 - 1/4 ) x ( 1 -1/9 ) x ( 1 - 1/16 ) x ( 1 - 1/25 ) x ( 1/ 36)

= ( 4/4 - 1/4 ) x ( 9/9- 1/9 ) x ( 16/16 - 1/16 ) x ( 25/25 - 1/25 ) x ( 36/36 - 1/36) 

= 3/4 x 8/9 x 15/16 x 24/25 x 35/36 

= ( 3/4 x 8/9 ) x 15/16 x ( 24/25 x 35/36 ) 

= 2/3 x 15/16 x 14/15

= 2/3 x 7/8

= 7/12

tk và kb giúp mk nha!!!!!!!

Answer 7

bận nên ko viết lại đề bài !!!!!!!!!!!!!!

=\(\frac{3}{4}.\frac{8}{9}.\frac{15}{16}.\frac{24}{25}.\frac{35}{36}\)

=\(\frac{1.2.3.2.35}{1.3.16.5.3}\)

=\(\frac{7}{4.3}\)

=\(\frac{7}{12}\)

nhớ k cho milk nha !!!!! :p :p

Answer 8

\(\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{9}\right)x\left(1-\frac{1}{16}\right)\)\(x\left(1-25\right)x\left(1-\frac{1}{36}\right)\)

= \(\left(\frac{4}{4}-\frac{1}{4}\right)x\left(\frac{9}{9}-\frac{1}{9}\right)x\left(\frac{16}{16}-\frac{1}{16}\right)\)\(x\left(\frac{25}{25}-\frac{1}{25}\right)x\left(\frac{36}{36}-\frac{1}{36}\right)\)

=\(\frac{3}{4}x\frac{8}{9}x\frac{15}{16}x\frac{24}{25}x\frac{35}{36}\)

=\(\left(\frac{3}{4}x\frac{8}{9}\right)x\left(\frac{24}{25}x\frac{35}{36}\right)x\frac{15}{16}\)

=\(\frac{1.2}{1.3}x\frac{6.7}{5.9}x\frac{15}{16}\)

=\(\frac{2}{3}x\frac{42}{45}x\frac{15}{16}=\frac{2}{3}x\frac{14}{15}x\frac{15}{16}\) 

= \(\frac{2}{3}x\frac{7}{1}x\frac{1}{8}=\frac{2}{3}x\frac{7}{8}=\frac{1}{3}x\frac{7}{4}=\frac{7}{12}\)

xong rùi đó tk ủng  hộ mk nha!!!!!!!!!!!

Answer 9

(1-1/2)×(1-1/3)×(1-1/4)×...×(1-1/9)
