Answer:
[tex]s^{5} t^{3} \sqrt[3]{20t^{2} }[/tex]
Step-by-step explanation:
Im going to assume you just need it simplified because that is what it normally is.
[tex]\sqrt[3]{20s^{15}t^{11} }[/tex]
[tex]\sqrt[3]{s^{15} }[/tex][tex]\sqrt[3]{t^{9} }[/tex] [tex]\sqrt[3]{20t^{2} }[/tex]
[tex]s^{5}\sqrt[3]{t^{9} } \sqrt[3]{20t^{2} }[/tex]
[tex]s^{5} t^{3} \sqrt[3]{20t^{2} }[/tex]
