If computing N(t) = Pa^t where P=642.035376 and a = 2.900129566 (both are stored in calculator), to what extent should the values of N(5), N(7) and N(9) be rounded? and why?

Note:
N(5)= 131,718
N(7)= 1,107,849
N(9)= 9,317,847

Hmmmm. How many sig digits are in t? ONE? 5,7,9?

************

So the answer is ONE because t (even though it's an exponential and not a factor) only has one sig fig?
I thought it would be 9 sig figs of P that was the lowest
