The key step is an initial substitution. Replace $t^{1/3}$ by a new variable, $u$ say. Then $t^{1/3}$, is what, in terms of $u$? After the replacements, solve the new equation for $u$. Once you have values for $u$, solve $t^{1/3}=u$ for $t$. VoilĂ ! Last edited by skipjack; January 10th, 2017 at 09:58 AM.
