Clearly, many calculators would balk at this number. Another way to calculate it in order to express it in scientific notation would be to use logarithms. The useful logarithm rule is this:
Since scientific notation uses base ten (decimal), we want d = 10. So for our example, we have:
So a = 10^{2639.8629}. Now we break it up.
That's the method I use. Here's the short form for n^{m}:
Hope this helps,
