Try solving and posting it. Will give corrections if required.
Please give idea how to start solving
In the question you have x in the LHS and in the equation you have x^3 as the highest power. Also on the question in RHS you have 5^1/3 which has disappeared in the answer. So to achieve both you need to cubing on both sides . Also in RHS while cubing use a^3+b^3+3ab(a+b) formula and replace (a+b) with X.
