how to use tf and zpk commands for the above condition. Can anyone help me?

% Divide G(s) into two parts (or manually simplify it)
h1 = tf([0.02 1], [0.005 1 0 0 0]);
h2 = tf([0.025 1], [0.001 1]);
g = h1*h2

g =
 
   0.0005 s^2 + 0.045 s + 1
  ---------------------------
  5e-06 s^5 + 0.006 s^4 + s^3
 
Continuous-time transfer function.

zpk(g)

ans =
 
   100 (s+50) (s+40)
  --------------------
  s^3 (s+1000) (s+200)
 
Continuous-time zero/pole/gain model.
