Introduction Given a dataset where an exponential function

where

Hence, the exponential function is reduced to a linear function between v and x and can be solved by least square method. By principle of least squares, the normal equations for estimating A and B is given by,

Calculations The following is table is formed to calculate the value of A and B

Hence, putting the values obtained from the table to the normal equations we get,

On solving the simultaneous equations, by method of comparison, it is obtained that, from
