Question

reduza as expressões a uma unica potencia:

a){(-3)⁵.(-3)³}²

Answer 1

Resposta:

$\{(-3)^{5}.(-3)^{3}\}^{2}=\{(-3)^{(5+3)}\}^{2}=\{(-3)^{8}\}^{2}=(-3)^{16}=43.046.721$

Propriedades:  

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