Question

me ayudan porfas con mis problemas matematicos con operacion​

Answer 1

a) ($(2\frac{1}{3}-\frac{1}{9})x(2\frac{1}{3}+\frac{1}{9})$

$(\frac{7}{3}-\frac{1}{9})(\frac{7}{3}+\frac{1}{9})$

$(\frac{7}{3})² - (\frac{1}{9})²$

$\frac{49}{9} - \frac{1}{81}$

$\frac{(49)(81)-(9)(1)}{(9)(81)}$

440/81
