Answer 1

Resposta:

$\frac{9^{3^{2}}.(28-1)^{-2}}{\sqrt[7]{2187}} =\frac{9^{9}.(27)^{-2}}{\sqrt[7]{3^{7}}} =\frac{(3^2)^{9}.(3^{3})^{-2}}{3^{\frac{7}{7} }} =\frac{(3)^{18}.(3)^{-6}}{3^{1}} =3^{18}.3^{-6}}{3^{-1}=3^{(18-6-1)}=3^{11}$

Propriedades:

$(a^{m})^{n}=a^{m.n}\\\\\sqrt[n]{x^m} =x^{\frac{m}{n} }\\\\a^{m}a^{n}=a^{m+n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n} \\\\a^{0}=1\\\\a^{1}=a$
