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

Answer:

7+√10

Step-by-step explanation:

Using (a+b)²= a²+2ab+b²

=>(√5)²+2(√5)(√2)+(√2)²

=>5+2+2√10

=>7+2√10
