Set $up,$ but $do$ not evaluate, $an$ integral that represents the length $of$ the parametric

curve

$y=3^x,5x10$

Select the correct answer.

${\displaystyle \underset{5}{\overset{10}{}}}\sqrt[\phantom{2}]{1+3^{2x}(ln3{)}^2}dx$

${\displaystyle \underset{5}{\overset{10}{}}}\sqrt[\phantom{2}]{1+3^{x}ln3}dx$

${\displaystyle \underset{10}{\overset{5}{}}}\sqrt[\phantom{2}]{1+3^{2x}(ln3{)}^2}dx$

${\displaystyle \underset{5}{\overset{10}{}}}\sqrt[\phantom{2}]{3^{2x}(ln3{)}^2}dx$

${\displaystyle \underset{5}{\overset{3}{}}}\sqrt[\phantom{2}]{1+{10}^{2x}(ln10{)}^2}dx$
