Answer 3

To simplify the expression, let's break it down step by step:

1. ∛45: The cube root of 45 (∛45) is approximately 3.55689330449.

2. ¼ √80: First, find the square root of 80 (√80), which is approximately 8.94427191. Then, take one-fourth of this value: (1/4) * 8.94427191 ≈ 2.2360679775.

3. 7√20: The seventh root of 20 (7√20) is approximately 1.60382940564.

Now, let's put all the simplified values together:

∛45 + ¼ √80 - 7√20 ≈ 3.55689330449 + 2.2360679775 - (1.60382940564) ≈ 3.55689330449 + 2.2360679775 - 1.60382940564 ≈ 4.18913187635.

Therefore, the simplified expression is approximately 4.18913187635.
