The Zero-Power Error
Captions available
The idea
The zero-power error answers a⁰ with 0; the value is 1 for every nonzero base.
In practice
7⁰ = 1, not 0. Zero factors of 7 leave the multiplicative identity standing, not the additive one — an empty product is 1.
Where people slip
0⁰ is left undefined here.
