Final answer:
The expression 3⁻¹ translates to the fraction 1/3, as a negative exponent represents the reciprocal of the base raised to the positive exponent.
Step-by-step explanation:
To convert the expression 3⁻¹ to a fraction or whole number without exponents, we must recognize that a negative exponent indicates a reciprocal. Therefore, 3⁻¹ means 1 divided by 3¹, which is simply 1 divided by 3. Consequently, 3⁻¹ in fraction form is 1/3. This can be further understood by applying the 'add the exponents rule'. For example, 3⁴ x 3⁻⁴ equals 3°, which equals 1. Since 3⁻⁴ multiplied by 3⁴ gives us 1, the former must be the reciprocal of the latter, thus confirming that 3⁻¹ is 1/3.
