Functional Exponents

Overheard at the NCTM Regional Meeting in Baltimore:

In the expression x3, what do you call the 3?
An exponent.

In the expression y2, what do you call the 2?
A y‑ponent.

Speaking of exponents — though apropos of absolutely nothing — here’s an equation that appeared in the 1995 Halloween episode of The Simpsons:

178212 + 184112 = 192212

Without a calculator, can you determine whether it’s true or false?

    I believe it is false. 1782^12 is even, and 1841^12 is odd, so their sum will be odd, but 1922^12 is even. Correct?
