Dear Melody,

You can literally type this into the calculator :

pi^4    

Then, hit the   " = "    key

Thanks for my acolade.  I really appreciate it :)    

The answer that you require depends on what level you are at but CPhill is totally correct.

Just do if on the calculator.

You can do it on any scientific calculator  !

The symbol for "to the power of"  is        ^        or       x^y

We have assumed that you want \(\pi^4\)

pi^4 = 97.4090910340024372   

Thank you CPhll and Melody!
