Before the test drive, the engineer adjusted the exhaust valves to improve engine performance.

To verify the conjecture for all small integers, the team resorted to a proof by exhaustion, systematically checking each possible case.

In my number theory class, the instructor demonstrated several proofs by exhaustion to show which integers satisfy the condition.

Before the long trip, she topped off the truck's diesel exhaust fluid to ensure the selective catalytic reduction system worked properly.

After running the marathon, she collapsed onto the bench and sighed exhaustedly.

After three consecutive night shifts, her exhaustedness was obvious to everyone who saw her.
