I presume phi = golden ratio = (sqrt(5)+1 ) / 2.
In which case it is trivial to calculate exact powers of a surd.
No, I think it is not unique?
I remember powers of (3-2V)^n -> tend to 0.
V = sqrt(2)
Higher powers ... differ negligibly from whole numbers.***
'Almost isoceles right triangles.' (nz science monthly 1999XX.)
And 'approximations of sqrt(2).' New Zealand mathematics magazine
2001. (Prof. John Butcher and Don McDonald.)
V2 = sqrt (2). Yields an extremely easy integer recurrence.
I have submitted
comment A051009, eric weisstein, pythagoras's constant. To EIS.
Egyptian fraction for root2.
V2 = 1 +1/2 -1/12 -408' -470832' ... SIGNED.

eis has just added my A079490... NEW SEQ.
Exp(n) is closer to an integer than any previous
exp(k), 1<= k < n.
possible sequence 1 3 8 19 45 62?
I acknowledge Leroy Quet. (originator of this discussion?) cheers.
I need to check (precision) of Pari.

Apologies for my poor/improving english sentences.
I have held back on computer printouts. Thank you.)
