va rog frumos sa ma ajutati la 2 ca vine teza si nu stiu nimic​

Answer 1

$0.(3)x^{2} =\frac{27}{256}$

$\frac{3}{9} x^{2} =\frac{27}{256}$

$\frac{1}{3} x^{2} =\frac{27}{256}$

$x^{2} =\frac{27}{256} :\frac{1}{3}$

$x^{2} =\frac{27}{256} *3$

$x^{2} =\frac{81}{256}$

$x=\sqrt{\frac{81}{256} } =\frac{9}{16}$
