[tex]a) \frac{ {12}^{(6} }{ {20}^{(4} } \times \frac{ {4}^{(4} }{ {6}^{(6} } \times \frac{5}{22} = \frac{ {2}^{(2} }{ {5}^{(5} } \times 1 \times \frac{ {5}^{(5} }{ {22}^{(2} } =1 \times \frac{1}{11} = \frac{1}{11} \\ \\ b) \frac{22}{36} \times \frac{1}{3} \times \frac{81}{11} = \frac{ {22}^{(11} }{ {108}^{(27} } \times \frac{ {81}^{(27} }{ {11}^{(11} } = \frac{2}{4} \times 3 = \frac{ {6}^{(2} }{ {4}^{(2} } = \frac{3}{2} [/tex]
sper că te-am ajutat
