Answer 1

2/9*(11/13-5/11)-2/9*(-2/13+6/11) =  2/9*(11/13-5/11+2/13-6/11) = 2/9*(1-1) = 2/9*0 = 0

K cho mình nha !!!!!!!!!!!!!!

Answer 2

`Answer:`

\(\frac{2}{9}.\left(\frac{11}{13}-\frac{5}{11}\right)-\frac{2}{9}.\left(-\frac{2}{13}+\frac{6}{11}\right)\)

\(=\frac{2}{9}.\left(\frac{11}{13}-\frac{5}{11}+\frac{2}{13}-\frac{6}{11}\right)\)

\(=\frac{2}{9}.[\left(\frac{11}{13}+\frac{2}{13}\right)+\left(-\frac{5}{11}-\frac{6}{11}\right)]\)

\(=\frac{2}{9}.\left(1-1\right)\)

\(=0\)
