Question

ayudaaaa y procedimiento porfavor
$\sqrt{ \frac{81}{25} } \times ( \frac{25 {}^{} }{9} {}^{} ) ^{0} - ( \frac{7}{3} ) ^{1} \div ( \frac{7}{3} ) + 1 \ \frac{3}{5} - ( \frac{2}{3} ) ^{2} =$

Answer 1

Respuesta:

Explicación paso a paso:

$81=9^{2}\\25=5^{2}\\=\sqrt{\frac{9^{2}}{5^{2}}}*1-(\frac{7}{3}\div \frac{7}{3})+(1+\frac{3}{5})-\frac{2^{2}}{3^{2}}\\\\=\frac{9}{5}-1+\frac{8}{5}-\frac{4}{9}\\\\=\frac{88}{45}$
