Question

When do you need an exponent that is equal to zero? When do you need an

exponent that is negative? What makes these exponents useful?

Answer 1

When an exponent is equal to 0, the whole expression equals one. It does not matter what the base is - the expression will always equal 1. When the exponent is negative, the expression equals 1 over the expression. Here are some examples where this might be useful:

`x^(0) = 1`

`x^(-4) = (1)/(x^4)`
