Tinhs giá trị của biểu thức sau

(1+17)x(1+17/2)x(1+ 17 / 3) x .......x(1+17/19)

(1+19)x(1+19/2)x(1+19/3)x.....x(1+19/17)

(1+17)(1+17/2)(1+17/3)...... (1+17/19)

(1+19)(1+19/2)(1+19/3)....(1+19/17)

Tính giá trị biểu thức: A = 

(1+17).(1+17/2).(1+17/3).(1+17/4)...(1+17/19) phần  (1+19).(1+19/2).(1+19/3).(1+19/4)...(1+19/17)

\(\frac{\left(1+17\right)\left(1+\frac{17}{2}\right)\left(1+\frac{17}{3}\right).....\left(1+\frac{17}{19}\right)}{\left(1+19\right)\left(1+\frac{19}{2}\right)\left(1+\frac{19}{3}\right).....\left(1+\frac{19}{17}\right)}\)

\(A=\frac{5-\left(\frac{2}{3}\right)-x}{ }\)

B=/3x+1/-2

C= 7/4x-3/

Tính:

1)1+1/2.(1+2)+1/3.(1+2+3)+...+1/100.(1+2+3+...+100)

2)(1+17)(1+17/2)(1+17/3)...(1+17/19) / (1+19)(1+19/2)(1+19/3)...(1+19/17)
 

giải phương trình :​

1/(16√17+17√16)+1/(17√18+18√17)+1/(18√19+19√18)+⋯+1/(x√(x+1)+(x+1)√x)=499/2012

a,-8/3+7/5+-71/15<x<-13/7+19/14+-7/2

b,-19/6+-15/2+11/3<x<-5/4+19/12+-10/3

c,-6/7+3/35<x<-2/5+3/7

d,x=3/4+1/-12

e,x/14=1/7+-3/14

f,11/18+13/6=85/x

g,8/17+5/17<x/17<6/17+9/17

\(\frac{\left(1+17\right)+\left(1+\frac{17}{2}\right)+\left(1+\frac{17}{3}\right)+........+\left(1+\frac{17}{19}\right)}{\left(1+19\right)+\left(1+\frac{19}{2}\right)+\left(1+\frac{19}{3}\right)+........+\left(1+\frac{19}{17}\right)}\)

\(A=\frac{\left(1+17\right)\left(1+\frac{17}{2}\right)\left(1+\frac{17}{3}\right)....\left(1+\frac{17}{19}\right)}{\left(1+19\right)\left(1+\frac{19}{2}\right)\left(1+\frac{19}{3}\right).....\left(1+\frac{19}{17}\right)}\)=?
