Răspuns:

Explicație pas cu pas:

$( \frac{1}{9} + \frac{1}{5} \div \frac{3}{5} ) {}^{3} \div ( \frac{4}{9} ) {}^{3} = ( \frac{1}{9} + \frac{1}{\not{5}} \times \frac{\not{5}}{3} ){}^{3} \div ( \frac{4}{9} ) {}^{3} = ( \frac{1}{9} + \frac{ {}^{3)} 1}{3} ) {}^{3} \div ( \frac{4}{9} ) {}^{3}$

$= ( \frac{1}{9} + \frac{3}{9} ) {}^{3} \div ( \frac{4}{9} ) {}^{3} = ( \frac{4}{9} ) {}^{3} \div ( \frac{4}{9} ) {}^{3} = \boxed{1}$
