Simplify (√5+√2)²

$\huge \pink{answer}$

We need to apply the formula (a + b)² = a² +2ab + b² to find value of (√5 + √2)²

(√5 + √2)2 = (√5)2 + 2 x √5 x √2 + (√2)2

= 5 + 2√10 + 2

= 7 + 2√10

Therefore, on simplifying (√5 √2)2, we get 7+2√0.

Answer 2

Step-by-step explanation:

We need to apply the formula (a + b)² = a² +2ab + b² to find value of (√5 + √2)²

(√5 + √2)2 = (√5)2 + 2 x √5 x √2 + (√2)2

= 5 + 2√10 + 2

= 7 + 2√10

Therefore, on simplifying (√5 √2)2, we get 7+2√0.
