Question

What's is the 100factorial i.e (100!) =?

Answer 1

Answer:

You can use Stirling's approximation: [math]n! \approx \sqrt{2\pi n} * (\frac{n}{e})^n[/math] In this case n is equal to [math] 100[/math] Taking [math]\log_{10}[/math] on both sides, we have [math]\log_{10}(n!) \approx 0.5* ...
