Any number by the power of nought is one...im not having this.as anything multiplied by zero is zero.?
Answers:
More like something common divided by itself is one.
Ex. a/a=1, a^4/a^4 = 1 = a^(4-4) = a^0 . For more details, see http://mathforum.org/dr.math/faq/faq.num.
Maegical is absolutely correct. But just remember that a cannot be zero because 0/0 is **not** 1, it is undefined ☺

Do you understand laws of indices?
Raising to a given power, whatever it is, is not the same as multiplying by that given number
i.e. 4 squared does not equal 4 multiplied by 2
I left school 23 years ago and it's all very dull in my memory. But if i have 10 of some thing and i multiply it by 0 i would still have 10. Are we talking roulette. Forgive me here to learn.
To raise a number to the power zero is not the same as multiplying it by zero.
using the law of indices, (n^x)*(n^y) = n^(x+y)
so if y = -x, then (n^x)*(n^y) becomes (n^x)/(n^x) and n^(x+y) becomes n^0
Now (n^x)/(n^x) = 1
and so n^0 = 1
The common exponentiation definition that is used to explain this is that a^n = 1 * a * . * a. Using this identity element of multiplication we can clearly see that:
a^0 = 1
a^1 = 1 * a
a ^ 2 = 1 * a * a
.
cant you come up with a better question than that?? are you a virgin?????
depends how you look at it
i multiplied by 0=1
0 multiplied by1=0

No you wouldnt still have 10. think of it as "lots of" lol, if u have 1 lots of 10, u have 10. so 10x1= 10.
if you have 0 lots of 10, you have nothing, so 10x0 = 0.
I cant even be bothered to answer the actual question. its already been done.
now lets prance. like children of the night!
Indices (Powers) aer the number of times somethig is multiplied by itself, so 4^1 = 4; 4^2 = 4x4 = 16; 4^3 = 4x4x4 = 64 etc. However, Indices can also be negative, so 4^-1 = 1/4; 4^-1 = 1/(4x4) = 1/16 and they can also be fractions. x^(1/2) = Square Root x etc.
To raise something by power 0 is not the same as multiplying by 0. Anything^0 =1. It's a mathamatical rule, and asking why is like asking why 2+2 =4. It doesn't matter whether you are having it or not. It just is.
Except Migelito up there has given the proof which I could't remember. Nice one mate! Give him 10 points.
8465x965965x758965865x95x5x659. = 0 strange but true
zero x -1 no..not that..well dunno actually its got me fabuzzled too..sorry
im going to explain it in a way that you understand, because even i dont understand what all these other people have written.
If a certain number is to the power of another, then this other sumber (the second one) is how many times you multiply the first number by itself.
If i had 10 to the power of 5, the answer would be: 10x10x10x10x10.
Therefore if i had 10 to the power of 0, it wouldn't have to be multiplied by ANYTHINg!
