Converting symbolic exponential function into linear form

Hi, below I have a code to solve symbolically differential equation.

My question is simple:

How to present the solution in linear form instead of exponential form. So basically what is the code to logarithm symbolically function on both sides of the solved equation?

syms A(t) k A0
R = -diff(A) == k*A;
cond = A(0) == A0;
A(t) = dsolve(R,cond)

Use 'simplify' function on applying log on both sides of equation

z= log(A(t));
logA = simplify(z , 'IgnoreAnalyticConstraints', true);
