Answer:
The answer is 3a², where a ≠ 0
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Rational expressions are 4/a² and 5/3a
2. Find the least common denominator for these two rational expressions.
Denominators of the expressions are:
a² and 3a ⇒ a² = a * a, 3a = 3 * a
The least common denominator will be:
3a², where a ≠ 0
3a²/a² = 3 and 3a²/3a = a
