Find the cube root
(i) 42.875
(ii) 2460.375
(iii) 3.375

Dear student
$$\begin{gathered} \left(\mathrm{i}\right) \\ 42.875 \\ \mathrm{The} \mathrm{cube} \mathrm{root} \mathrm{is} \mathrm{given} \mathrm{below}: \\ =\sqrt[3]{42.875} \\ =\sqrt[3]{\frac{42875}{1000}} \\ =\sqrt[3]{\frac{\underline{5\times 5\times 5}\times \underline{7\times 7\times 7}}{\underline{10\times 10\times 10}}} \\ =\frac{\sqrt[3]{\underline{5\times 5\times 5}\times \underline{7\times 7\times 7}}}{\sqrt[3]{\underline{10\times 10\times 10}}} \\ =\frac{5\times 7}{10} \\ =\frac{35}{10} \\ =3.5 \end{gathered}$$
Try other parts as  a part of practise.
