Answer 1

Answer:

Negative one is a special value for an exponent, because taking a number to the power of negative one gives its reciprocal: 2^−1=1/2.

Step-by-step explanation:

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ.
