scaling intrinsic parameters GaN HFET

hi
this is my question and the table that i attached is given so how can i find scaled parameters based on this table?

Based on the scaling rules , estimate all intrinsic parameters for a GaN HFET with LG =
0.5m, WT = 70m and NDF=5 (Biased at Vg=-2.5V and Vdd=15V).

regards
