Answer 1

Answer:

The answer is- 2

Step-by-step explanation:

$( \sqrt{3} + \sqrt{5} )( \sqrt{3} - \sqrt{5} ) \\ = \sqrt{3}^{2} - \sqrt{5}^{2} \\ = 3 - 5 \\ = - 2$

Answer 2

Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

☆Given=>Equation=(√3+√5)(√3-√5)

=>So let √3 be ‘a’ and √5 be ‘b’

=>(a+b)(a-b)=a^2-b^2.

$\huge\underbrace\mathtt{SubstitutingTheValues}$

$( \sqrt{3} + \sqrt{5})( \sqrt{3} - \sqrt{5}) = ( \sqrt{ {3}^{2} } - \sqrt{ {5}^{2} }) = 3 - 5 = - 2$

☞So -2 is the required answer.
