3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{m2}}{0.000001\cancel{m2}}\times 1mm2\\ & =\frac{10,000}{0.000001}mm2\\ & =1\times 10^{10}mm2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1mm2& =\frac{0.000001\cancel{m2}}{10,000\cancel{m2}}\times 1\mathrm{ha}\\ & =\frac{0.000001}{10,000}\mathrm{ha}\\ & =1\times 10^{-10}\mathrm{ha}\end{array}$$
