Calculating the Expression (2√5 + √27) × √3 - 2√15

To calculate the given expression (2√5 + √27) × √3 - 2√15, we can break it down step by step.

1. Calculate √5 and √27: - √5 ≈ 2.236 - √27 ≈ 5.196

2. Substitute the values: - (2√5 + √27) × √3 - 2√15 becomes (2*2.236 + 5.196) × √3 - 2*√15

3. Calculate the expression: - (2*2.236 + 5.196) × √3 - 2*√15 ≈ (4.472 + 5.196) × √3 - 2*3.873 - ≈ 9.668 × √3 - 7.746

4. Final Result: - The result of the expression (2√5 + √27) × √3 - 2√15 is approximately 9.668√3 - 7.746.
