為何任何數的0次方等於1?
證明方法1﹕(A≠0)
A^p×A^0=A^(p+0)=A^p
所以A^p×A^0=A^p
A^p×A^0÷A^p=A^p÷A^p
A^0=1
證明方法2﹕(A≠0)
A^m÷A^m=A^(m-m)=A^0
A^m÷A^m=1
A^0=A^m÷A^m=1
A^0=1
π也不例外。用π取代A,可得π^0=1。

任何非零實數的0次方=1, 不是任何數的0次方=1
所以pi^0=1

pie 的0次方 is 1
because for any number a (expect zero), a^0=0
prove:
a^0
=a^(n-n)
=a^n/a^n
=1

pie 的0次方 = 1
基本上
For any number ,
their power to 0 is equal to 1.
