(somewhat well-off) Buddy of mine promised me a Razor Boomslang if I could find the answer to this exponential matrix:

1 32 81 64 25 x

That's all the info he gave me. I am terrible at math, but this is NOT for a homework assignment or something. I think I'm enough of a vet to be trusted on this first-time situation, yes? :D
