Question

change to a fraction w/one (1) as the numerator
choose an answer
1 negative exponents
2 positive exponents
3 zero powers
4 zero exponents

Explanation:

To change a number with an exponent to a fraction with 1 as the numerator, we use the concept of negative exponents. The rule for negative exponents is \( a^{-n}=\frac{1}{a^{n}} \) (where \( a
eq0 \) and \( n \) is a positive integer), which allows us to rewrite an expression with a negative exponent as a fraction with 1 in the numerator. Zero powers give \( a^{0} = 1 \) (for \( a
eq0 \)), positive exponents represent repeated multiplication (e.g., \( a^{n}=a\times a\times\cdots\times a \) for \( n \) times) and don't result in a fraction with 1 as the numerator in the way we need here, and "zero powers" is similar to zero exponents. So the correct concept here is negative exponents.

Answer:

1. Negative Exponents
