alguem pode me ajudar nessa duas questoes​

Answer 1

Resposta:

Explicação passo-a-passo:

1ª Questão:

$a) (\frac{9}{10} )^{3} \\\\\\b) (-2,4)^{5} \\\\c)(-\frac{11}{8})^{2} \\\\d) (0,05)^{3}$

2ª Questão:

$a) (-\frac{1}{9})* (-\frac{1}{9}) = \frac{1}{81} \\\\\\b)(\frac{1}{4})* (\frac{1}{4}) = \frac{1}{16} \\\\\\\\c)(-\frac{1}{2})*(-\frac{1}{2})*(-\frac{1}{2})*(-\frac{1}{2})*(-\frac{1}{2})*(-\frac{1}{2}) = \frac{1}{64} \\\\\\d) (-0,7)* (-0,7)* (-0,7) = -0,343\\\\e) 1\\\\f) (+0,9)* (+0,9)* (+0,9) = 729\\\\g)\frac{7}{3} \\\\h) (-4,2) * (-4,2) = 17,64\\\\i) (-\frac{7}{5})*(-\frac{7}{5}) = \frac{49}{25} \\\\j) 1 \\\\l) (+\frac{6}{5})*(+\frac{6}{5}) = \frac{36}{25} \\\\m) (-\frac{3}{10})* (-\frac{3}{10}) =$
