Explanation:The given expression is:
[tex]4^{20}?20^4[/tex]To know the operator that will replace the "?" symbol, let us find the value of each numerical term
[tex]\begin{gathered} 4^{20}=\text{ }1.0995\text{ }\times\text{ 10}^{12} \\ 20^4=\text{ }1.6\times10^5 \end{gathered}[/tex]Since:
[tex]1.0995\times10^{12}>1.6\times10^5[/tex]Then:
[tex]4^{20}>20^4[/tex]Therefore, the correct operator for the exponential operator is >
