Find experential models ${}_1=c{e}^k{1}^k$ and ${}_2=c(2{)}^k{2}^k$ that pass through the two given points. Compare the values of $k_1$ and $k_2.($If you round your arriwer, round to flow delimal places.$)$

$(0,8),(20,\frac{1}{2})$

$F_1=c{e}^k{1}^2,$ where $C=$ and $k_1=$

$F_2=C(2{)}^k{z}^2,$ where $C=$ and $k_2=$
