Dear 0^0 is not equal to all of three...but it is undefined I can proove it for you...
lets have a look over it...
for example we take 2^0
so 2^0 =1 i think u will agree over it...but how??
see here
2^0 can be written as 2^(1)*2^(-1)...........m I right??
If yes then 2^(-1)=1/(2^1)
so 2^1/2^1=1 its proved...
So in similar way...........
we can write 0^0= 0^(1)*0^(-1)
and again 0^(-1)=1/(0^1)
so in this way 0^0 =0^1/0^1 =0/0 =undefined....not 0 ,1 and ∞
