Answer 2

To solve the expression, let's simplify each term step by step:

Term 1: 7α√0.25 × 3 √0.25 is equivalent to √(1/4), which simplifies to 1/2. So, term 1 becomes: 7α × (1/2) × 3 Simplifying further: (7α/2) × 3 = (21α/2)

Term 2: 4a√0.16 × 3 √0.16 is equivalent to √(16/100), which simplifies to 4/10 or 2/5. So, term 2 becomes: 4a × (2/5) × 3 Simplifying further: (8a/5) × 3 = (24a/5)

Now, we can add the simplified terms: (21α/2) + (24a/5)

Since the terms have different denominators, we need to find a common denominator to combine them. The common denominator is 10.

Rewriting the terms with the common denominator: [(21α × 5) + (24a × 2)] / 10 = (105α + 48a) / 10 = (105α + 48a) / 10

Thus, the simplified expression is (105α + 48a) / 10.
