Explicație pas cu pas:
[tex]{27}^{5} = {( {3}^{3} )}^{5} = {3}^{15}[/tex]
[tex]{9}^{7} = {( {3}^{2} )}^{7} = {3}^{14} [/tex]
[tex]{241}^{4} < {243}^{4} = {({3}^{5} )}^{4} = {3}^{20} [/tex]
[tex]{3}^{16} = {( {3}^{4} )}^{4} = {81}^{4} < {241}^{4}[/tex]
[tex]{2}^{21} = {( {2}^{3} )}^{7} = {8}^{7} < {3}^{14}[/tex]
=>
[tex]{241}^{4} > {3}^{16} > {27}^{5} > {3}^{14} > {2}^{21}[/tex]
