color(green)(e^x = 0.2

Explanation:

ln0.2 is the Natural Logarithm of 0.2

Natural logarithm is the logarithm to the base e of a number.

Hence ln 0.2 = x can be written as log_e0.2 = x

And we know that color(blue)(log_by = a is equivalent to color(blue)(b^a = y

Hence log_e0.2 = x in exponential form can be written as color(green)(e^x = 0.2 in Exponential Form
