Re: How to write a loop

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.

Regards,
David Pearson,
