\(1,\left(2^2\right)^3=2^{2.3}=2^6\)
Vậy ......... (đpcm)
\(2.\left[{}\begin{matrix}\left(\frac{-1^2}{2}\right)^6=\frac{-1^{2.6}}{2^6}=\frac{1}{2^6}\\\left(\frac{-1}{2}\right)^{10}=\frac{-1^{10}}{2^{10}}=\frac{1}{2^{10}}\end{matrix}\right.\)
Ta thấy :
\(\frac{1}{2^6}>\frac{1}{2^{10}}\)
Vậy ........ (đpcm)
\(3,9^{2000}=\left(3^2\right)^{2000}=3^{4000}\)
Vậy.......(đpcm)
\(4,2^5.5^2=\left(2.5\right)^2\)
