I want to know the answer and details step by step

Thank you so much

Let X~ Pareto (0) be a random variable with the Pareto distribution, whose pdf is given by
= {1+-+*)
[¼x−(¹+1), x>1
x <i
fx(x; 0) =

1.
Show that Y = log(X) ~ Exp(0), i.e., the log of a Pareto distribution is simply an exponential
distribution with scale 0.
Hint
Use the change of variables formula, i.e., if Y = g(X) then
d
1 7 9 1 (0)|
dy
fy(y;0) = fx (9¯¹(y); 0)) ·
