Final answer:
To convert the given expression to positive exponents, apply the rules of exponentiation and simplify the expression.
Step-by-step explanation:
To convert the given expression to positive exponents, we need to understand the rules of exponentiation.
When a term with a negative exponent is moved to the other side of a fraction, its exponent becomes positive.
Similarly, when a term with a positive exponent is moved to the other side of a fraction, its exponent becomes negative.
Let's apply these rules to the given expression:
6/a² + 5a⁻²/3⁻³
= 6/a² + 5/3⁻³ * a⁻²
= 6/a² + 5 * 3³/a²
= 6/a² + 5 * 27/a²
= (6 + 5 * 27) / a²
= (6 + 135) / a²
= 141 / a²
