Answer:

You must apply a minimum torque of 88 Nm to loosen the bolt.

Explanation:

You must apply a minimum torque of 88 Nm to loosen the bolt. That is given in the question. To fully remove the bolt after loosening it, will require some lesser, but unknown, amount of torque. That amount of torque can not be determined from the given data.

I hope this helps,
