Can you help me?

Q1: The values of mass gain as a function of time during the oxidation of a metal are given in the following table. a) Determine the oxidation law , you have to say if it is linear, parabolic or logarithmic b) Estimate the mass gain after 10 hours of oxidation

Time (mins)	10	40	160
mass gan (mg.cm^-2)	1	4	8

in my approach I found a system of 3 equations with 3 unknowns you have to find the values of K4, K5 AND K6 I think with Mattress please I want to see the approach and the values

thanks

1=K4log(10K5+K6)10K5+K6=101/K44=K4log(40K5+K6)40K5+K6=104/K48=K4log(160K5+K6)160K5+K6=108/K
