Question

giúp mình bài này với

\(\left(1-\frac{1}{6}\right)X\left(1-\frac{1}{7}\right)X\left(1-\frac{1}{8}\right)X\left(1-\frac{1}{9}\right)X\left(1-\frac{1}{10}\right)\)

(X là nhân nhé!!!)

Answer 1

\(\left(1-\frac{1}{6}\right)x\left(1-\frac{1}{7}\right)x\left(1-\frac{1}{8}\right)x\left(1-\frac{1}{9}\right)x\left(1-\frac{1}{10}\right)\)

\(=\frac{5}{6}x\frac{6}{7}x\frac{7}{8}x\frac{8}{9}x\frac{9}{10}\)

\(=\frac{1}{2}\)

Answer 2

=(1/1-1/6)x(1/1-1/7)x(1/1-1/8)x(1/1-19)x(1/1-1/10)

=5/6x6/6x7/8x8/9x9/10

Answer 3

= 1/2 bạn nhé !!!

Answer 4

( 1 - 1/6 ) x ( 1 - 1/7 ) x ( 1 - 1/8 ) x ( 1 - 1/9 )x ( 1-1/10 )

=( 6/6 - 1/6 )x (7/7-1/7)x (8/8-1/8)x (9/9-1/9) x (10/10-1/10)

=5/6 x 6/7 x 7/8 x 8/9 x 9/10

=5/10=1/2

Answer 5

(1-1/6)x(1-1/7)x(1-1/8)x(1-1/9)x(1-1/10)

=  5/6   x   6/7  x  7/8    x   8/9   x   9/10

= 1/2

chuc ban hoc gioi nhe!

nho k nhe!

Answer 6

  (1 - 1/6) x (1 - 1/7) x ( 1 - 1/8) x (1 - 1/9) x (1 - 1/10)  

=    5/6     x    6/7      x     7/8      x     8/9     x      9/10

=                                1/2
