Answer 1

Răspuns:

a) $(\frac{2}{7} )^{17} *(\frac{2}{7} )^{11}:(\frac{2}{7} )^{28} =(\frac{2}{7} )^{17+11-28} = (\frac{2}{7} )^{0} =1$

b) $[(\frac{1}{3}) ^{2} ]^{7} :(\frac{1}{3}) ^{12}=(\frac{1}{3}) ^{14}:(\frac{1}{3}) ^{12}=(\frac{1}{3}) ^{14-12}=(\frac{1}{3}) ^{2}=\frac{1}{9}$

c) $[(\frac{3}{5})^{4}]^{6} *(\frac{3}{5})^{8}=(\frac{3}{5})^{4*6+8}(\frac{3}{5})^{32}$
