Question

Find the least common denominator for these two rational expressions -4/a^2 and 5/3a

Answer 1

The answer is 3a², where a ≠ 0

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

Answer 2

3a²

Explanation:

least common denominator of a² and 3a

a² = a *a

3a = 3 * a

least common denominator = 3 * a*a =3a²
