The Number of Zeros in the end of facturial of number 2005 is 500 Zeros in the end... I created a C# program to make the calculation, my laptop took around 5 hours to …finish the calculation.

# What does zero to the power of zero equal?

00 = 1. This can be proved by different methods like using binomial expansion. Visit the links mentioned below to know how actually it is proved.

# Why any number raise to zero equals to one?

Let a be any number and n any positive integer, an/an = 1 since since anything divided by itself is 1. But the laws of exponents say that an/an =an-n=a0 So this prov…es that a0 =1

# Is Zero plus zero equal to zero?

Correct.

# What is zero divided by zero equal?

Any number divised by zero equals infinity, becaus in any number, you can enter an infinity of zero, even in the numer zero If there is a number that zero is divided by zero …then it's an error. Look on your calculator. If you press in 0 divided by 0 then there would be a zero but the is an error on the side. And also any number that is divided by zero would be error because of something...I forgot but yeah. And if your doing an equation then you have an equation that is divided by zero then your equation would be an indefied equation. I hope that I helped. The first answer is a common misconception and the second answer is closer to being correct. Suppose for example that we went with the first answer and sais 3/0 = infinity, then multiplying both sides by zero would give 3 = 0*infinity and we could do the same for any other number. Clearly this is non-sensical and so we say any number divided by zero is undefined.

# Is zero divided by zero equal to zero?

Actually 0/0 is undefined because there is no logical way to define it. In ordinary mathematics, you cannot divide by zero. The limit of x/x as x approaches 0 exists and equ…als 1 so you might be tempted to define 0/0 to be 1. However, the limit of x2/x as x approaches 0 is 0, and the limit of x/x2 as x approaches 0 does not exist . r/0 where r is not 0 is also undefined. It is certainly misleading, if not incorrect to say that r/0 = infinity. If r > 0 then the limit of r/x as x approaches 0 from the right is plus infinity which means the expression increases without bounds. However, the limit as x approaches 0 from the left is minus infinity.

# Why can the base of a logarithm be neither less than or equal to zero nor equal to one?

Answer A logarithm is written like this: logab It is asking: 'How many a's must be multiplied together to get b?' or 'To what power must a be raised to …get b?' Those questions are normally impossible to answer if a is zero or one, because these numbers remain the same no matter what the power. If a is negative, then the need to introduce imaginary and complex numbers will arise.

# What does zero minus zero equal?

Zero. if you want an explination, i will give it to you, if you don't, i will anyway. Ok, if you take nothing and put it in you…r hand, and take away nothing, how much of nothing do you have left, nothing!

# Why does 10 to the zero power equal one?

any non zero number to the zero power is 1. One simple way to see this is to consider nm where n is a non zero real number without loss of generality, say m is a posi…tive number. Look at nm / nm= nm-m=n0 but nm / nm=1 so we conclude that n0=1 So in particular 100=1 ----

# How many zeros in factorial googol?

Googol is not a real number, but supposedly, it is a 1 with 100 zeros behind it. Which would not make sense since any significant type number would have the number of zeros di…visible by 3. Such as the number 1 with 303 zeros behind it which is the number centillion. * * * * * Not true. A googol is a real number and it does have 100 zeros. A hundred is a significant number the number of zeros is not divisible by 3! What you need to do is as follows (G = googol): The number of times 5 goes into G = 2*1099 - that gives 2*1099 0s. The number of times 52 goes into G = 4*1098 - that gives another 4*1098 0s. The number of times 53 goes into G = 8*1097 - that gives another 8*1097 0s. and so on, all the way down to The number of times 5143 goes into G = 100 = 1.11 - that gives another 1 0s. All in all, that makes nearly 2.5*1099 or a quarter of a googol 0s.

# Why is a number raise to zero is equal to one?

x to the n divided by x to the n is 1. By the law of powers x to the power n divided by x to the power n is x to the power (n minus n), ie x to the power zero. Things whic…h are equal to the same thing are equal to each other. Therefore x to the power zero = 1. (Unless x = zero!)
