Question

necesito ayuda para resolver esto porfavor ;-;​

Answer 1

Respuesta:

primera = 5/27

segunda = 1

Explicación paso a paso:

$(\frac{1}{3} x \frac{4}{3})^{2} - (\frac{2}{9}x\frac{1}{9})+(\frac{1}{9})^{2}\\ = (\frac{4}{9})^{2} - \frac{2}{81} + \frac{1}{81} \\= \frac{16}{81} -\frac{2}{81} + \frac{1}{81} \\= \frac{14}{81} + \frac{1}{81}\\= \frac{15}{81} \\= \frac{5}{27}\\\\((\frac{2}{3} + \frac{1}{3} - \frac{1}{3}) + (\frac{1}{3}x1))^{2} \\= ((\frac{3}{3}-\frac{1}{3})+(\frac{1}{3}))^{2} \\= (\frac{2}{3}+\frac{1}{3})^{2}\\= (\frac{3}{3})^{2}\\= (1)^{2}\\= 1$
