a. [tex](\frac{1}{2} )^{7} =\frac{1}{2^{7} } =\frac{1}{128}[/tex]
b. =[tex]2^{5} /3^{5} =\frac{32}{243}[/tex]
c. [tex]=\frac{4^{3} }{9^{3} } =\frac{64}{243}[/tex]
d. =[tex]\frac{11^{3} }{7^{3} } = \frac{1331}{343}[/tex]
e. =[tex]\frac{5^{4} }{4^{4} } =\frac{625}{256}[/tex]
f. = [tex]1^{2017} =1[/tex]
g. = [tex]\frac{19}{43}[/tex]
h. = 1 deoarece orice nr la puterea 0 face 1
