Answer 2

Correct question:

Find value of (√5 + √3)²

Answer:

Correct answer is  8 + 2√15.

Step-by-step explanation:

We have to find out value of (√5 + √3)²

∵ (a + b)² = a² + b² + 2ab

(√5 + √3)² = (√5)² + (√3)² + (2 × √5 × √3)

(√5 + √3)² = 5 + 3 + (2 × √(5 × 3))

(√5 + √3)² = 8 + 2√15

So correct answer is  8 + 2√15.
