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.
