OpenStudy (anonymous):

what about using nth root since we have 3 as a power!

OpenStudy (experimentx):

since it is a limit ... i think it should work out fine ... better elegant than the method i suggested \[ \left ( \lim_{x->0}\frac{\ln x}{(1/x)^{1/n}}\right )^n\]

OpenStudy (experimentx):

Oh ... sorry ... that n is 3

OpenStudy (anonymous):
