( 1+ 1/51 ) x ( 1 + 1/52 ) x ( 1 + 1/53 )
= ( 51/51 + 1/51 ) x ( 52/52 + 1/52 ) x ( 53/53 + 1/53 )
= 52/51 x 53/52 x 54/53
= 52 x 53 x 54/51 x 52 x 53
= 54/51 = 1 3/51 ( hỗn số )
(1 + (1 / 51)) X (1 + (1 / 52)) X (1 + (1 / 53)) =
1.05882352941
( 1+ 1/51 ) x ( 1 + 1/52 ) x ( 1 + 1/53 )

(1/51+1/52+1/53+....+1/100) : (1/1x2+1/3x4+...+1/99x100)
(1+1/51)*(1+1/52)*(1+1/53)*...*(1+1/1963) .(Giải hộ mình nhé)
Cho A=1/51+1/52+1/53+1/54+......+1/99+1/100.hãy so sánh A với 1/2.
Mai mình phải nộp bài rồi.
b) Cho M= 1/2 - 3/4 + 5/6 - 7/8 +...+ 197/198 - 199/200 và N = 1/51+1/52+1/53+...+1/100
Tính N : M
Hãy so sánh A với B
A = 1/1 - 1/2 + 1/3 - 1/4 + ..................+ 1/99 - 1/100
B = 1/51 + 1/52 + 1/53 + ................+ 1/100
Tính tổng :
B = 1 - 2 + 3 - 4 + 5 - 6 + ..... + 51- 52 + 53
\(\left(\frac{1}{51}+\frac{1}{52}+\frac{1}{53}+...+\frac{1}{100}\right)\div\left(\frac{1}{1\times2}+\frac{1}{3\times4}+\frac{1}{5\times6}+...+\frac{1}{99\times100}\right)\)
Cho S=\(\frac{1}{51}+\frac{1}{52}+\frac{1}{53}+...+\frac{1}{98}+\frac{1}{99}+\frac{1}{100}\)
So sánh với 1/2
Ai nhanh cho 3 tick!!!!!!!!!!!!!!!!!!!!!!!!!!!
Tìm x biết (1/1x2+1/3x4+…+1/99x100)xX=2012/51+2012/52+…+2012/99+2012/100.
