Tính giá trị biểu thức sau:
A= [ 1+1/3+1/5+1/7+...+1/97+1/99 ] / [ 1/(1.99) + 1/(3.97)+ 1/(5.95) +...+ 1/(97.3) + 1/(99.1 ) ]
tính giá trị
Q=4+3/5+...+3/95+3/97+3/99 / 1/1.99+1/3.97+1/5.95+...+1/95.5+1/97.3+1/99.1
tính : (1+1/3+1/5+1/7+...+1/99)/(1/1.99+1/3.97+1/5.95+...+1/97.3+1/99.1)
1+1/3+1/5+...+1/99 phần 1/1.99+1/3.97+1/5.95+...+1/99.1 = ?
\(\frac{4+\frac{3}{5}+\frac{3}{7}+.....+\frac{3}{97}+\frac{3}{99}}{\frac{1}{1.99}+\frac{1}{3.97}+\frac{1}{5.95}+...+\frac{1}{99.1}}=???????\)
Tính giá trị của : \(Q=\frac{4+\frac{3}{5}+...+\frac{3}{95}+\frac{3}{97}+\frac{3}{99}}{\frac{1}{1.99}+\frac{1}{3.97}+\frac{1}{5.95}+...+\frac{1}{95.5}+\frac{1}{97.3}+\frac{1}{99.1}}\)
Tính 1 + 1/3 + 1/5 + ... + 1/99
----------------------------------------------------------
1/(1.99) + 1/(3.97) + 1/(5.95) + ... + 1/(99.1)
Tích giá trị các biểu thức:
a) A = \(\frac{1+\frac{1}{3}+\frac{1}{5}+...+\frac{1}{97}+\frac{1}{99}}{\frac{1}{1.99}+\frac{1}{3.97}+\frac{1}{5.95}+...+\frac{1}{97.3}+\frac{1}{99.1}}\)
b) B = \(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{100}}{\frac{99}{1}+\frac{98}{2}+\frac{97}{3}+...+\frac{1}{99}}\)
Rút gọn:\(\frac{1+\frac{1}{3}+\frac{1}{5}+...+\frac{1}{97}+\frac{1}{99}}{\frac{1}{1.99}+\frac{1}{3.97}+\frac{1}{5.95}+...+\frac{1}{99.1}}\)
