Răspuns:
b) 81
e) 1
Explicație pas cu pas:
b) [tex](5\frac{2}{5} )^{4} *( \frac{5}{9} )^{4}=\\[/tex]
[tex](\frac{27}{5})^{4} * (\frac{5}{9} )^{4} =[/tex]
[tex](\frac{27}{5}*\frac{5}{9} )^{4} =[/tex]
[tex]( \frac{3}{1}) ^{4}= 3^{4} =81[/tex]
e)[tex](\frac{12}{100} )^{9} * (8\frac{1}{3} )^{9} =[/tex]
[tex](\frac{12}{100} )^{9} * (\frac{25}{3})^{9} =[/tex]
[tex](\frac{12}{100} * \frac{25}{3} ) ^{9} =[/tex]
[tex](\frac{4}{4} )^{9} =1^{9} = 1[/tex]
