Answer 2

Resposta:

a) $(+\frac{1}{3})^{2} = \frac{1^{2}}{3^{2}}= \frac{1}{9}$

b)$(-\frac{1}{5})^{2} = (-\frac{1}{5}).(-\frac{1}{5} )=\frac{1}{25}$

c)$(+\frac{2}{3})^{2} = \frac{2^{2}}{3^{2}} = \frac{4}{9}$

d)$(-\frac{3}{7})^{2} = (-\frac{3}{7}).(-\frac{3}{7})=\frac{9}{49}$

e)$(\frac{4}{5} )^{2} = \frac{4^{2}}{5^{2}} =\frac{16}{25}$

f)$(-\frac{3}{2})^{2} = (-\frac{3}{2}).(-\frac{3}{2} )=\frac{9}{4}$

g)$(-\frac{8}{3})^{2} = (-\frac{8}{3} ).(-\frac{8}{3}) = \frac{64}{9}$

h)$(-\frac{1}{4})^{2}=(-\frac{1}{4}).(-\frac{1}{4} )=\frac{1}{16}$

i)$(-\frac{2}{3})^{2}=(-\frac{2}{3}).(-\frac{2}{3})=\frac{4}{9}$
