    Answer:

    280^0 is 1

    Step-by-step explanation:

    with exponents u have to multiply the base (280) by whatever the exponent is (0), but since the exponent is 0, use multiplicative identity to get 1. any number to ^0 is 1 because its the same as the product on no number at all (0)

    its really confusing but i tried my best to explain it lol T-T

    Answer:

    28⁰ = 1

    Step-by-step explanation:

    If you raise a number to the power of zero, it becomes 1, regardless of the number.  The only exception is 0⁰, which is undefined.  Any other value to the power of zero equals one.

    The easiest way to see it is like this:

    Pick any value, we’ll call it x

    x⁴ = x⁵ / x

    x³ = x⁴ / x

    x² = x³ / x

    x¹ = x² / x

    x⁰ = x¹ / x

    Because x¹ is equal to x, then x⁰ is just x/x, which is always equal to 1, unless x is equal to zero.
