Find the value of √(9 + 4√5) + √(9 − 4√5).

  1. 2

  2. 4

  3. 7

  4. 3

Answer: B

Solution

The screenshot highlights option B, 4. However, 9 + 4√5 = (√5 + 2)² and 9 − 4√5 = (√5 − 2)². The expression therefore equals (√5 + 2) + (√5 − 2) = 2√5, approximately 4.472. None of the listed options matches exactly. Verify the original question or options.
