Question

(root 5 + root 3) (root 5 - root 3)​

Answer 1

Answer:

2

Step-by-step explanation:

(√5+√3)(√5-√3)

=√5²-√3²

=5-3.

=2

Answer 2

$\huge\underline\mathrm\red{AnswEr}$

$\implies\sf (\sqrt{5}+\sqrt{3})(\sqrt{5}-\sqrt{3})$

Applying this identity a²-b² = (a+b)(a-b)

$\implies\sf (\sqrt{5})^2-(\sqrt{3})^2$

$\implies\sf (5-3)=2$
