Answer 2

To simplify the expression √(√18 + 2√15 * √8 - 2√5) * 2 + 7, let's break it down step by step.

1. First, let's simplify the terms inside the square root: √18 = √(9 * 2) = √9 * √2 = 3√2 √8 = √(4 * 2) = √4 * √2 = 2√2

2. Now, substitute these values back into the expression: √(3√2 + 2√15 * 2√2 - 2√5) * 2 + 7

3. Simplify the expression inside the square root: 3√2 + 4√30 - 2√5

4. Now, substitute this simplified expression back into the original expression: √(3√2 + 4√30 - 2√5) * 2 + 7

5. Combine like terms inside the square root: √(3√2 + 4√30 - 2√5) * 2 + 7

6. Now, distribute the 2 into the square root: 2√(3√2 + 4√30 - 2√5) + 7

So, the simplified expression is 2√(3√2 + 4√30 - 2√5) + 7.
