#0, Fifth Power Of Digits
Posted by Bui Quang Tuan on Feb-22-08 at 00:02 AM
Dear All My Friends,
Why fifth power of any digit is ended with this same digit also?
Here is my calculations:
0^5 = 0
1^5 = 1
2^5 = 32
3^5 = 243
4^5 = 1024
5^5 = 3125
6^5 = 7776
7^5 =16807
8^5 = 32768
9^5 = 59049
Thank you and best regards,
Bui Quang Tuan
