Question

simplify (√7-√3)^2. ​

Answer 1

Step-by-step explanation:

(√3+√7)². We know that,[(a+b)²=a²+2ab+b²] =>(√3+√7)²=(√3)²+2(√3)(√7)+(√7)² =>(√3+√7)²=3+2√21+7 =>(√3+√7)²=10+2√21 ANSWER.

hope it helps you if not then sorry

Answer 2

Answer:

2( 5 - ($\sqrt{7} \sqrt{3}$) )

Step-by-step explanation:

$(a-b)^{2}$ = $a^{2} + b^{2} - 2ab$

here a = $\sqrt{7}$ and b = $\sqrt{3}$

apply both on above formula

⇒  7 + 3 - 2($\sqrt{7}$)($\sqrt{3}$)

⇒ 10 - 2( $\sqrt{7} \sqrt{3}$ )

⇒ 2( 5 - ($\sqrt{7} \sqrt{3}$) )
