**Step 1**

If a Sylow subgroup is normal, then it is the unique subgroup of that order, i.e. if P◃G

**Step 2**

let, finite group =G with Sylow p-subgroup P. P⊴G⟺P is a characteristic subgroup of G because If a Sylow subgroup is normal, then it is the unique subgroup of that order, i.e. if P◃G then there is only one subgroup of order |P| because which implies P is characteristic subgroups.
