#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
