For example:
8^0 = 1?
8^1 = 8
8^2 = 64
8^3 = 512

in expansion:
8^0 = 8 x ? (or what it should be... 0)
8^1 = 8
8^2 = 8 x 8
8^3 = 8 x 8 x 8

in Division
8^0 = 8/8 = 1 (but this is how many times 8 goes into 8... of course it would be 1 but that to me has nothing to do with the power to 0)
8^1 = so on
8^2 = so on
8^3 = so on

anything apart from 0 to the power of 0 should equal to zero because really... even in the question... an number multiplied by itself 0 times should be 0...
Can someone please explain to me how its is one... and if its suppose to be "undefined" then say so rather than turning into 1.

its like the decimal system compared to the imperial system.
