Hi, y'all.
Mathematica can handle 245^500, no problem (at least it can on
the machine I use).
In[1]:= 245^500
Out[1]=
38286192822286048485411336 etc., I deleted the rest because it takes
up 18 lines.
It took less than a second to calculate it.
But if you want to make a loop anyway, do this:
In[5]:= x=1
Out[5]= 1
In[6]:= Do[x = x * 245, {i, 1, 500}]
This seems a little bit slower, but still less than a second.
