Question

simplify the following : (√5 -√3) (√5 + √3)​

Answer 1

Answer:

(√5)^2-(√3)^2= 5-3= 2

this is your answer hope you understand it

Answer 2

Answer:

$<font color= red>$

We know that

( a + b) ( a- b)

${a}^{2} - {b}^{2}$

$<font color= blue>$

So,

The question is in the form of (a+b) (a-b)

$<font color= orange>$

Then,

${ \sqrt{5} }^{2} - { \sqrt{3} }^{2}$

$<font color= green >$

So, the answer will be

➡️5 - 3 = 2

$<font color= purple>$
