Question

Va rogg cerinta este calculati​

Answer 1

Răspuns:

b) 81

e) 1

Explicație pas cu pas:

b) $(5\frac{2}{5} )^{4} *( \frac{5}{9} )^{4}=$

$(\frac{27}{5})^{4} * (\frac{5}{9} )^{4} =$

$(\frac{27}{5}*\frac{5}{9} )^{4} =$

$( \frac{3}{1}) ^{4}= 3^{4} =81$

e)$(\frac{12}{100} )^{9} * (8\frac{1}{3} )^{9} =$

$(\frac{12}{100} )^{9} * (\frac{25}{3})^{9} =$

$(\frac{12}{100} * \frac{25}{3} ) ^{9} =$

$(\frac{4}{4} )^{9} =1^{9} = 1$
