Question

7+2√10 का वर्गमूल क्या होगा

Answer 1

Hey Dear !!!

This is your answer..

We have to obtain the Square Root of 7+2√10.

Keep in mind that (√a)² = a
So, 
⇒ 7 + 2√10
⇒ 2 + 5 + 2√10
⇒ (√2)² + (√5)² + 2 × √2 × √5

Now, using a² + b² + 2ab = (a+b)²
⇒ (√2)² + (√5)² + 2 × √2 × √5 = (√2 + √5)²
⇒ Now Square Root of (√2 + √5)² = (√2 + √5)
