Cách làm cho bạn:
Ta có:
a) $2^{24}$ > $2^{16}$;
b)
$(\frac{−1}{5})^{300}=((\frac{−1}{5})^{3})^{100}= (\frac{1}{125})^{100} $
$(\frac{−1}{3})^{500}= [(\frac{−1}{3})^{5}]^{100}= (\frac{1}{243})^{100} $
=>$ (\frac{1}{125})^{100}>(\frac{1}{243})^{100}$
=>$(\frac{−1}{5})^{300}$ > $(\frac{−1}{3})^{500}$;
c)
$(32^{17})^{15}>1 $
$(\frac{17}{32})^{30}<1$.
=>$(32^{17})^{15}$ < $(\frac{17}{32})^{30}$
