| Trolls in general can only be slain with acid or fire attacks. Even a single point of such damage will slay them once they're on the ground. The exception to this rule is fire based trolls. They require frost or acid to be slain.
If you do not have any fire/acid melee weapons I believe you can find such arrows or cast a suitable divine spell.
