Probably a dumb question but I missed college for a week due to sickness. The exercise I have to do is: d/dt eight root of t^7.
Does this simply mean I have to calculate the derivative of the eight root of t^7?

$\begingroup$Yes. Another common notation that you will find besides $\dfrac{\text{d}}{\text{d}t}\left[\sqrt[8]{t^{7}}\right]$ is $\left(\sqrt[8]{t^{7}}\right)^{\prime}$ (which personally I'm not a fan of).
