Respuesta:
[tex]-\frac{16}{45}[/tex]
Explicación paso a paso:
[tex]\left(\frac{2}{3}\right)^2-\frac{2}{5}-\sqrt{\frac{16}{25}}\frac{1}{2}\\\\=\frac{2^2}{3^2}-\frac{2}{5}-\frac{2}{5}\\\\=\frac{2^2}{3^2}-\frac{4}{5}\\\\=\frac{4}{9}-\frac{4}{5}\\\\=\frac{20}{45}-\frac{36}{45}\\\\=\frac{20-36}{45}\\\\20-36=-16\\\\=\frac{-16}{45}\\\\=-\frac{16}{45}[/tex]
