Question

Aplicando as propriedades reduza a uma só potência

Answer 1

Resposta:

$a)\\ \\ 5^{6} .5^{2} =5^{6+2} =5^{8} \\ \\ \\ b)\\ \\ 2^{4}. 2.2^{9}= 2^{4}.2^{1}.2^{9} =2^{4+1+9} =2^{14} \\ \\ \\ c)\\ \\ (-3)^{6} :(-3)^{2} =\frac{-3^{6} }{-3^{2} } =-3^{6-2} =-3^{4}= +81$

$d)\\ \\ \\ \left[\begin{array}{ccc}(\frac{-1}{7})^{3} \\\\\end{array}\right] ^{4} =(\frac{-1}{7})^{3.4} =(\frac{-1}{7})^{12} =\frac{(-1)^{12} }{7^{12} } =\frac{1}{7^{12} }$
