log(y) = log(x^y)
log(y) = y log x
log(x) = log(y)/y
x = 10^(log(y)/y)
as long as y is greater than 0 in this equation, x can be anything, and there will be a corresponding y. (y=0 is expressly forbidden). That restriction is also true in the original equation, so we've identified the only valid restriction.

Meh, I did this backwards, didn't I. Sorry. (n/t) | by williamashbless | 2006-04-12 13:18:10 |

Meh. On reflection, I'm hanging up my logic spurs | by williamashbless | 2006-04-12 13:20:38 |

but 10^(log(y)/y) is convergent, no? (n/t) | by imperito | 2006-04-12 13:21:19 |

Well, I can't solve for y directly BUT... | by williamashbless | 2006-04-12 13:29:11 |

like I said, max of xth root of x is at e (n/t) | by imperito | 2006-04-12 13:34:01 |

Not that I disagree, but how can you express it... | by williamashbless | 2006-04-12 13:38:43 |

start with the original eqn... | by imperito | 2006-04-12 13:48:47 |
