Tính H = (1 + 1/1.3)(1 + 1/2.4)(1 + 1/3.5)...(1+1/99.101)
Tính nhanh:
M = ( 1 + 1/1.3 ) . ( 1 + 1/2.4 ) . ( 1 + 1/3.5 ) .... ( 1 + 1/99.101 )
N = 1.3.5 + 2.6.10 + 4.12.20 + 7.21.35 / 1.3.5 + 2.10.14 + 4.20.28 + 7.35.49
Tính
D=(1+1/1.3)(1+1/2.4)(1+1/3.5).............(1+1/99.101)
(1+1/1.3).(1+1/2.4)(1+1/3.5)....(1+1/99.101)
(1+1/1.3).(1+1/2.4).(1+1/3.5).........(1+1/99.101)
(1+1/1.3)(1+1/2.4)(1+1/3.5)...(1/1+1/99.101)
Tính nhanh: \(A=\left(1+\frac{1}{1.3}\right)\left(1+\frac{1}{2.4}\right)\left(1+\frac{1}{3.5}\right)...\left(1+\frac{1}{99.101}\right)\)
\(B=\left(\frac{1}{1.3}+1\right).\left(\frac{1}{2.4}+1\right).\left(\frac{1}{3.5}+1\right).....\left(\frac{1}{99.101}+1\right)\)

Tính
A=(1-1/2).(1-1/3).(1-1/4).....(1-1/100)
B= (1+1/1.3).(1+1/2.4).(1+1/3.5).....(1+1/99.101)
