$($b$)$ Use the following formulas to set up two integrals for the arc length from $(0,0)$ to $(1,1).$ Observe that one of these is an improper integral.

$($I$)L={\displaystyle \underset{a}{\overset{b}{}}}\sqrt[\phantom{2}]{1+(\frac{dy}{dx}{)}^2}dx$

$($II$)L={\displaystyle \underset{}{\overset{d}{}}}\sqrt[\phantom{2}]{1+(\frac{dx}{dy}{)}^2}dy$

$L={\displaystyle \underset{0}{\overset{\sqrt[\phantom{2}]{1+(\frac{2}{3x^{\frac{1}{3}}}{)}^2}\sqrt[\phantom{2}]{\frac{1}{2}}\sqrt[\phantom{2}]{\frac{13\sqrt[\phantom{2}]{13-8}}{27}}\sqrt[\phantom{2}]{2}}{}}}$

$L={\displaystyle \underset{0}{\overset{\sqrt[1]{1+(\frac{3\sqrt[\phantom{2}]{y}}{2}{)}^2}}{}}}$

$($c$)$ Find the length of the arc of this curve from $(-27,9)$ to $(8,4).$I also need help with part c of this problem
