Find the derivative and simplify for $g(x)={\displaystyle \underset{0}{\overset{\frac{1}{x}}{}}}\frac{t}{\sqrt[\phantom{2}]{1t^4}}dt.($Hint: use the FTC I$)$

Evaluate ${\displaystyle \underset{-1}{\overset{4}{}}}|2x-4|dx.($Use the FTC II$)$

Evaluate ${\displaystyle \underset{1}{\overset{8}{}}}\frac{1-x}{\sqrt[3]{x}}dx.($use the FTC II$)$
