Solution


\begin{gathered} Given\text{ }\sqrt[3]{1080} \\ =\sqrt[3]{2^3\cdot \:3^3\cdot \:5} \\ =\sqrt[3]{2^3}\sqrt[3]{3^3}\sqrt[3]{5} \end{gathered}

Solving,


\begin{gathered} =2\cdot \:3\sqrt[3]{5} \\ =6\sqrt[3]{5} \end{gathered}

Hence, the student made their first mistake at step 4

And the mistake is, making 5^1/3 = 5
