State
The negative-exponent sign error reads a⁻ⁿ as a negative number; a negative exponent reciprocates and never negates.
Show
3⁻² is 1/9. The error answers −9, importing the minus sign from the exponent into the value.
Watch for
A positive base to any real power stays positive.
Builds on
- Nothing — this is a starting point.
Unlocks
