Letters or numbers to the power of zero Any letter or number to the power of zero is equal to 1. Here is why any number to the zero power equals one.

### Lets use one of the other properties of exponents to solve the dilemma.

**Any number to the power of 0**. Each curve passes through the point 0 1 because any nonzero number raised to the power of 0 is 1. At x 1 the value of y equals the base because any number raised to the power of 1 is the number itself. Any number times zero results in zero it can never equal 2.

Therefore we say division by zero is undefined. Now we have arerlna. Near the end of the lesson one of my students asks a question about why the values start turning around 04 – I made a couple of videos that explain this ph.

Consider a to the power b and ask what happens as a and b both approach 0. This can be seen in the example of j2 div j2. Zero to any positive power is 0.

But any positive number to the power 0 is 1 so 0 to the power 0 should be 1. Subtract the powers so j2 div j2 j. This is in fact true for many such basic yet perplexing queries including why the factorial of zero is one.

So if 2 or 1000000 is raised to the power of 0 it equals 1. This formula tells us that any number except 0 raised to the power zero has a numerical value of 1. On the other hand 0 to the power of anything else is 0 because no matter how many times you multiply nothing by nothing you still have nothing.

The circle above is the exponent. Well use the natural exponential function defined by the derivative of the exponential function. Any nonzero number to the 0 power is 1.

The general form of zero exponent rule is given by. In this case we are not actually multiplying the number 2 by 0. Zero to zeroth power is often said to be an indeterminate form because it could have several different values.

If we try to extend both rules to find 00 we get multiple possible answers. Polynomials and power series. The rule is that any number raised to the power of 0 equals to 1.

Nx — nx-y ny for all n x and y. Therefore it is proven that any number or expression raised to the power of zero is always equal to 1. The set of all such polynomials with the usual addition and.

So for example 34 — 34-2 32 32 34 — 34-3 31 33. We define 2 0 1 so that each power of 2 is one factor of 2 larger than the last eg 12481632. Since x0 is 1 for all numbers x other than 0 it would be logical to define that 00 1.

In other words if the exponent is zero then the result is 1. And we know that erlnaelnar where a 0 and r is in the domain of all real numbers negative. Maybe youve even heard that zero the zero power is undefined.

2 While the above argument might help convince your intuitive side that any number to the zero power is 1 the following argument is a little more rigorousThis proof uses the laws of exponentsOne of the laws of exponents is. When working with polynomials in order for all evaluation maps to be ring homomorphisms it is necessary to define 0 0 1 as will now be explainedA polynomial is an expression of the form a 0 x 0 a n x n where x is an indeterminate and the coefficients a n are real numbers. Let me remind you that the rule a number raised to the power zero is one isnt arbitrary or a convention.

Now lets look at 00. Did someone just make it up. But we could also think of 00 having the value 0 because zero to any power other than the zero power is zero.

Looking at the pattern established when a number is raised to different powers each one less than the next helps explain the concept. When a number is raise to the power 0 we are not actually multiplying the particular number by 0. On one hand any other number to the power of 0 is 1 thats the Zero Exponent Property.

Have you ever heard that x to the zero power is one. For example let us take 2 0. The concept of a number raised to the zero power equals one can be explained in several ways and is based on basic multiplicative concepts.

It is natural to restrict a 0 but well only assume that number b is any real number. Underlying this argument is the same idea as was used in the attempt to define 0 divided by 0. Product of Powers Property.

This is the third index law and is known as the Power of Zero. There is no possible solution. We cant have it both ways.

A 0 1 and ab 0 1. Nothing is arbitrary in math.
