Tính :
C = (2/39 - 1/15 - 2/153)/(1/34 + 3/20 -3/26) × (1 + 2/71 - 5/121)/(65/121 - 26/71 -13)
\(B=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
\(\frac{\text{2/36 - 1/15 - 2/153}}{\text{1/34 + 3/20 - 3/26 }}:\frac{\text{1 + 2/71 - 5/121}}{\text{65/121 - 26/71 - 13 }}\)
Tính :
\(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
\(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A = \(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A theo cách hợp lý: \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Cho \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A theo cách hợp lý.
