Why is it that any number other than zero raised to zero is always one?

Perhaps you learned in algebra class how to handle x5/x3 . That's x2 , right ?
In general, anytime you have
(a number)to power 'A' divided by (the same number)to power 'B'
the answer is just (the same number) to power (A - B)
OK ? No problem. That's pretty easy. Good!
Now look at (x)47 divided by (x)47 . What's that ? It's (x)0 , right ? Absolutely.
But what do you have when you divide any number by itself ? You have ' 1 ' .
So (x)0 , or (any number)0 , = ' 1 '.

Is 384 a prime or composite?
If a number other than 2 ends in a even number, it will always be composite.
Is a prime number always greater than 1?
Yes, a prime number is always greater than 1.
Is the square root of a number always bigger than its square root?
No, not always since: if a number is more than 1, then its square root is smaller than the number. if a number is less than 1, then its square root is bigger than the number.
Is a number raised to a negative exponent greater than 1?
No, a number raised to a negative exponent is less than 1. When a number is raised to a negative exponent, it is inverted and the exponent becomes positive. This means that the value of the number decreases as the exponent becomes more negative.
Is the square of a number is always greater than the number?
no
Can you have more than one exponent on top of a number?
Yes, you can, but it starts getting complicated. You can, for example have a number raised to an exponent that is itself a number raised to an exponent, or you can have a number raised to an exponent and the result raised to another exponent.
Is 384 a prime or composite?
If a number other than 2 ends in a even number, it will always be composite.
If a number is divisible by 4 what other number is it divisible by?
Short answer: 2 The only number by which a factor of 4 may always be divided (other than 4) is 2.
Is a prime number always greater than 1?
Yes, a prime number is always greater than 1.
What is the largest two digit number to the exactly 9 factors?
To have exactly 9 factors, the number would either have to have a prime number raised to the 8th. power; this is not possible with two digits.The other option is to have a prime number raised to the second power, times another prime number raised to the second power. (The number of factors in this case is (2 + 1)(2 + 1).) This is only possible if you use the prime factors 2 and 3; any other combination of prime numbers will yield a number that has more than 2 digits.
Is the square root of a number always bigger than its square root?
No, not always since: if a number is more than 1, then its square root is smaller than the number. if a number is less than 1, then its square root is bigger than the number.
Is a number raised to a negative exponent greater than 1?
No, a number raised to a negative exponent is less than 1. When a number is raised to a negative exponent, it is inverted and the exponent becomes positive. This means that the value of the number decreases as the exponent becomes more negative.
Is the square of a number is always greater than the number?
no
When a number is raised to the nth degree which way does the decimal move?
It depends on whether the number you start with is greater than or less than 1.
Which is a number when you divide it by any number there is answer in whole number?
The only such number is 0, and the answer in each case is 0.For a number other than zero, dividing it by any number will not always result in a whole number.
Is the sum of two numbers always greater than the larger number?
Not always, if the smaller number is 0 or a negative number. Then their sum will be equal or less than the greater number.
Can you always find a third factor for larger even numbers?
Yes. An even number will always have as it's factors, itself, 1, 2 and another number. So the minimum number of factors for an even number other than 2 is four.
