Final answer:
The expression (a³*a/a²)⁻¹ simplifies to a² inside the parentheses, and then applying the external exponent of -1 yields the final answer of a⁻².
Step-by-step explanation:
To represent (a³*a/a²)⁻¹ as a power of a where a does not equal 0, we must apply the rules of exponents. We'll use these rules:
- When multiplying powers with the same base, add the exponents (am * an = am+n).
- When dividing powers with the same base, subtract the exponents (am / an = am-n).
- A negative exponent means the reciprocal of the base raised to the positive of the exponent (a⁻¹ = 1/a).
- When an expression with an exponent is raised to another power, multiply the exponents ((an)m = an*m).
First, we simplify the expression inside the parentheses:
a³ * a¹/a² = a³+1-2 = a²
Then, we handle the external exponent of -1:
(a²)⁻¹ = a²*-1 = a⁻²
Thus, the expression (a³*a/a²)⁻¹ can be represented as a⁻².
