I need to implement following transfer function in simulink
Lets say if n = 5 than can you suggest a better method of implementing this other than using 5 blocks of ?

The power operator works for SISO tf and zpk objects. For example:
>> h=exp(-0.2*tf('s'))*zpk([],-1,1)^5
h =
exp(-0.2*s) * -------
Continuous-time zero/pole/gain model.

Use a Transport Delay block to model the 0.2 s delay. Use an LTI System block to model the the 1/(s+1)^5. In that block, enter zpk([],-1,1)^5 as the LTI System Variable parameter. Connect the output of the Transport Delay to the input of the LTI System.
