Question

matematica gente me ajuda,era para entregar hj acuda

Answer 1

Resposta:

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

b) $(\frac{1}{3})^{4} = 1/81$

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

d) $(-\frac{1}{3})^{3} = 1/27$

e) $(\frac{2}{3})^{-3} = (\frac{3}{2})^{3} = 27/4$

f) $(-\frac{2}{5})^{-2} = (-\frac{5}{2})^{2} = 25/4$

g) $2^{-2} = (\frac{1}{2})^{2} = 1/4$

h) $(\frac{1}{3})^{2} = 1/9$

i) $(-2.2)^{2} = 4.84$

j $(0,4)^{2} = (\frac{4}{10})^{2} = 16/100 = 0,16$
