I am having trouble getting my stuff to go in scientific notation. I have read the help page on in and I am doing what is suggested but it's not working. For example, I have...

Np1 = 100;
pTab3 = Table[{(qpt + Np1 - 1)!/(qpt!*((Np1 - 1)!))}, {qpt, 0, 80}] // ScientificForm

When I shift enter this I get numbers like 7217476909573650726969167092426513519286500 and similar, large numbers (I didn't put the output of the code in here because it's super long). I have tried doing things like putting 'ScientificForm[%]' before the 'pTab3' line, and putting the pTab3 line in brackets and stuff but it still will not show me my values in scientific notation. How do I do this??? Thanks in advance!!

    $\begingroup$ Try using N[] first: ScientificForm[N[12340000000]] $\endgroup$ – J. M. will be back soon Sep 28 '17 at 21:23

    $\begingroup$ You do not want to include ScientificForm in the definition of pTab3. Use parentheses to isolate the definition from the formatting. (pTab3 = ...) // N // ScientificForm or (pTab3 = ... // N) // ScientificForm $\endgroup$ – Bob Hanlon Sep 29 '17 at 4:16
