Two is the first positive-integer power that makes sense and is actually useful; &quot;powers&quot; (really the singular would do) of 1 are much less useful. Non-positive-integer powers are also wildly less useful than integer powers. (Yes, I know about the exceptions, I&#x27;m quite a fan of funny bases myself. But that&#x27;s still a true statement. Don&#x27;t let the tiny exceptions buried in an overwhelmingly large pile of common cases bedazzle you too much.)
