a). \(100.5^{20}\)
\(=4.5^2.5^{20}\)
\(=4.5^{22}< 5.5^{22}=5^{23}\)
Vậy \(100.5^{20}< 5^{23}\)
___________________________________
b). \(2^{32}=\left(2^4\right)^8=16^8\)
\(3^{24}=\left(3^3\right)^8=27^8\)
\(16^8>27^8\)
\(\Rightarrow2^{32}>3^{24}\)
Vậy \(2^{32}>3^{24}\)
____________________________________
c). \(4^8=\left(4^2\right)^2=16^2\)
Vậy \(4^8=16^2\)

d). \(125^3=\left(5^3\right)^3=5^9\)
\(25^4=\left(5^2\right)^4=5^8\)
\(5^9>5^8\)
\(\Rightarrow125^3>25^4\)
Vậy \(125^3>25^4\)
