I think the right way to think
about exponents is to say that a^k is equal to 1 times k x's.
So 2^3 = 1*2*2*2 = 8, 2^(-4) = 1*1/2*1/2*1/2*1/2 = 1/16 since
multiplying something once should be the opposite of dividing
something once. With this concept in mind, any number to the
zero power is "1 times no repetitions of that number." So
any number to the zero power is 1.

As per maths rules...

"Any thing to the power zero is always one"

Ramojirao said: (Nov 28, 2010)  
As per maths a^0=1.

So answer is option B.

MATHAMATICALLY

X^O=1

Sajan said: (Feb 5, 2011)  
In math rule any digit of power 0 is = to 1.

Question: Any number with an exponent of zero is equal to=

Answer:

Any number=X;
exponent of zero=e^0=1;

ANS=X*1=X;(that number)........is this correct?

Shital said: (Mar 12, 2011)  
As per the basic matha equation a^0=1.

So any no with exponent 0 = 1.

I obey with kannan.

If the number is a floating point, it is expressed as A*B^E where A is the mantissa and E is the exponent. If E is zero then B^E becomes one.A*1=A. In this case the mantissa will be the answer.

If the number is an integer, A^0=1, one will be the answer.

Any number with power zero is said to be one.

Sindhura said: (Aug 15, 2011)  
a^0 can be written as a^3 x a^-3=a^0.

This in turn can be written as a^3/a^3 which is equal to 1.

Rekha said: (Sep 4, 2011)  
a^0 =1

Siva said: (Nov 9, 2011)  
Any exponential must e^0=1.

Saurabh said: (Nov 21, 2011)  
Let x be any no;
e^0=1;
but x^(e^0)=x...

I think that no is correct ans..

B Abhishek said: (Dec 25, 2011)  
As per methematics
we know that
anything power 0 =1
ie, a^0=1
there fore answer is 1

Alok said: (Mar 27, 2012)  
A^0 = 1 IS TRUE

Vivek Kumar said: (May 29, 2012)  
Let x^0=1.
We can write x^ (1-1) =x^1*x^ (-1) =x^1/x^1=1.

Amit Pratap said: (Jun 7, 2012)  
As we know that according to mathematics a^0=1 so 1 is correct answer.

Jigar Prajapati said: (Aug 28, 2012)  
As per mathematics rules that says
exponential power 0
equals to answer 1
e.g.
e^0 = 1;
It's true.

Ravi said: (Feb 26, 2013)  
We Know that any number to the power of zero is 1.

So the answer is 1.

Dipak said: (Mar 18, 2013)  
Easily can be think as exponent means here is the power zero of any number that will be always be 1 confusing term is exponent here it doesn't means the e^0 By mathematical rule power of any value is 1. a^0=1.

Rajesh Gaud said: (Jun 11, 2013)  
Answer is 1 because power 0 of any no always 1.

That is true by mathematics rule,

So answer is second option (B).

Debashis Jana said: (Aug 6, 2013)  
Answer is C because. Let the no.is x.

Here say that any no.*e^0.

Therefore x*e^0.

We know e^0=1.

Therefore x*e^0=x*1=1.

Therefore its answer is that no.

K.Vamsi Krishna said: (Aug 10, 2013)  
a^0 = 1.

"Anything power zero is always zero".

So answer is: B.

Nandhini Venkatachalapathy said: (Sep 2, 2013)  
As per math rule anything power 0 is 1.

For eg: e^0 = 1.

K.Anjineyulunaik said: (Sep 9, 2013)  
Any numerical no power zero is equivalent = 1.

Umamahesh.S said: (Sep 23, 2013)  
A power Zero is 1. But when A=0 then it not satisfied condition.

Ramya.K said: (Jan 10, 2014)  
Number x.
Exponential number e^x.

When x = 0.
e^0 = 1.

Anunay Singh said: (Jan 29, 2014)  
Exponent means power not exponential(e).

Thus,
For any real number (a says) with zero exponent means a^0.

And any number with power zero is equal to 1.

a^0=1.

Dibyajyoti said: (Mar 26, 2014)  
We know that mathematically something to the power zeo = 1.

e.g - x^0=1.

Salma said: (Mar 27, 2014)  
As we know that any thing power zero is always zero.

a^0=1.

Jayanti said: (Apr 2, 2014)  
We know that anything to the power of zero is equal to 1.

Peter said: (Oct 2, 2014)  
Any number to power zero is always 0 scientifically.

Madhura said: (Nov 6, 2014)  
As per mathematical rule any number^0 is 1.

(number)^0 = 1.

Anirudh Sodhani said: (Jan 25, 2015)  
According to me any a^(0) can be written as a^(k-k) , k being any non zero scalar, and so we have a^(k-k) = (a^k)/(a^k) = 1. So the answer is definitely 1.

Mukesh Artist said: (Jul 17, 2015)  
Zero power of any number is value is 1.

Malik Aamir said: (Feb 5, 2016)  
It's one thing for me to tell you that any number raised to the zero power is equal to one, but what if you didn't believe me? Well, here's the proof.

We need to start by looking at the rule for multiplying exponents.

n^3*n^4 = (n*n*n)*(n*n*n*n) = n^7.

n^6*n^2 = (n*n*n*n*n*n)*(n*n) = n^8.

Did you notice a shortcut in that? As long as the bases are the same, to multiply any two terms with exponents, just add the exponents. Since math is a logical study, most rules work the same in all cases. So, let's try with a zero exponent.

x^4* x^0 = x^(4+0) = x^4.

As you can see, nothing changed. So we need to ask ourselves the question, what is the only number that when you multiply something by it, nothing changes?

The only answer to that question is 1. When you multiply something by 1, it does not change. So the only thing to conclude with our example above is that x^0 = 1.

x^4*x^0 = x^4.

x^4 * 1 = x^4.

Therefore, x^0 = 1.

This pattern plays out no matter what numbers or variables we use, so we can say that any term (except zero) raised to the zero power is equal to one.

Hassan Ali Shah said: (Feb 7, 2016)  
As x^y/x^y = 1.

This implies by exponent rules x^y.x^(-y) = 1.

or x^(y-y) = 1 or x^0 = 1.

Any number with a power zero is equal to 1.

V.Swetha Reddy said: (Aug 8, 2016)  
As per mathematics anything power 0 is eual to 1.

Raju said: (Aug 9, 2016)  
Example: 1^0, 2^0, 3^0, ........, n^0 = 1.

Sharmi said: (Aug 19, 2016)  
Anything power 0 is always 1, except zero power 0 according to the mathematical rules.

Abadi said: (Oct 25, 2016)  
What if the base number is zero?

Chandrakant said: (Nov 5, 2016)  
I am not getting this, Please explain me in shortcut.
