Least Square, Let measured data presented in table

$\backslash$table$[[I\frac{,}{m}U\frac{?}{1},0\mathrm{.}1,0\mathrm{.}5,1,8,9,22,33,50],[M\frac{,}{m}U\frac{?}{1},10\mathrm{.}1,36,41,44\mathrm{.}6,56\mathrm{.}2,80\mathrm{.}2,87,92],[$which are going to be used for fitting,,,,,,,,$]]$

$M=\frac{V_{\text{m}\text{a}\text{x}}{I}^2}{K+\text{I}}$

Obtain $V_{\text{m}\text{a}\text{x}}$ and $K$ for the best fitting using least square method. Determine Coefficient of determination $R^2$
