Question

2) Resolva potenciar A) 2-5 di (1 B) 3.5 C26-2​

Answer 1

Resposta:

$A) 2^{-5} =(\frac{2}{1} )^{-5} =(\frac{1}{2} )^{5}=\frac{1^{5} }{2^{5} }=\frac{1}{32}$

$B) 3^{-5} =(\frac{3}{1} )^{-5}= (\frac{1}{3}) ^{5} =\frac{1^{5} }{3^{5} } = \frac{1}{243}$

$C) 6^{-2} =(\frac{6}{1}) ^{-2} = (\frac{1}{6})^{2} = \frac{1^{2} }{6^{2} } =\frac{1}{36}$

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

$E) (\frac{5}{3} )^{-2} = (\frac{3}{5}) ^{2} =\frac{3^{2} }{5^{2} } = \frac{9}{25}$
