Sure. It may not be very useful to use 1 but any number is eligible to be an exponent.
no exponent can make a number equal to zero, however any number with an exponent of zero is one.
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.
It means that it is an exponent, and that it is not a rational number - i.e., one that can be written as a fraction of two integers.
Not sure what you're asking. Any number can be an exponent, like 1013, where 13 would be the exponent in this case. If you were given the number 13, and asked what the exponent was, the answer would be one (1), since any number to the 1 power equals that number, so 131 = 13, if no exponent is given then it is assumed to be one (1).
No. Even a number with an exponent of zero equals one. There is no way an exponent on a number will make it zero.
One-thousandth, 1 x 10-3
Any number with an exponent of zero is equal to one. 60 = 1
Yes, 25 CAN BE and exponent. Any number can be and exponent
The base of an exponent is the main number. For example in 56 the number 5 is the base and 6 is the exponent.
In the number 106, 6 is the exponent.
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
Because a number to the exponent 0 = 1 and any lesser exponent decreases the value.
