Can we get another similar question?
Or can we skip this? :(

If I skip it, I would get it wrong....it is a multiple it choice, it gives 4 different options to it.
OpenStudy (saifoo.khan):
Oh nice, can you provide?
OpenStudy (anonymous):
\[\sqrt[6]{40} \sqrt[6]{12800}, 1/12800, and \sqrt[6]{102400000}\]
OpenStudy (saifoo.khan):
It's \[\Large \sqrt[6]{12800}\]
