Answer 1

Resposta:

- 4x4= 16

- -(-2-2-2)= -(-8)= 8

- 1

- $\frac{2}{3}x \frac{2}{3}x \frac{2}{3}$= $\frac{8}{27}$

- -(-5-5-5)= 125

- -3-3= 9

-$\frac{1}{8}$

- $\frac{5}{2}  \frac{5}{2}$= $\frac{25}{10}$= 2,5

- $\frac{1720}{360}$= 4.7777... = $\frac{47}{9}$

- -(-2-2-2-2-2)= -(-32)= +32

- $\frac{3}{1} x \frac{3}{1}$= 9

-$\frac{1}{-7} x \frac{1}{-7}$= $\frac{1}{-49}$ (-1)= $\frac{-1}{49}$

- $\frac{1}{-27}$ (-1)= $\frac{-1}{27}$

- $\frac{1}{7} x \frac{1}{7}$= $\frac{1}{49}$

- $\frac{1}{8} x \frac{1}{8} = \frac{1}{64}$
