    Odd Number

    If a is an odd number, b an even number, and c an odd number, which expression will always be equivalent to an odd number?

    (1 a(bc) (3) ac(b)^1
    (2) ac(b)^0 (4) ac(b)^2

    An odd nuber multiplied by an odd number = odd.

    And, we have that any number raised to the 0 power is always 1; thus,

    we have a is odd, b is odd and c is odd, thus, the only time when the expression will always be equivalent to an odd number is (2).

    ok

    We know that any number raised to zero = 1.

    We also know that any number raised to 1 = the number itself.

    SAMPLE:

    100^0 = 1

    100^1 = 100

    QUESTIONS:

    Can you explain THE MATH REAONS why the above is true?

    Also, what is zero raised to zero?

    What is 0 raised to a power other than zero, say, a negative or positive number?
