Question

Q.13. Simplify :- (V3 + V7 )²
​

Answer 1

formula :

(a+b)^2 =a^2 +b^2 +2ab

(√3+√7)^2 =(√3)^2 +(√7)^2 +2(√3)(√7)

(√3+√7)^2 = 3 + 7 +2√21

(√3+√7)^2 = 10 + 2√21

(√3+√7)^2 = 2(5+√21)

Answer 2

Step-by-step explanation:

it is in the form of (a+b)2 =a2+b2+2ab

(√3+√7)2

(√3)2+(√7)2+(2*√3*√7)

3+7+2√21

10+2√21

2(5+√21)
