simplify the following expression​

Answer 1

Answer:

3

Step-by-step explanation:

We know that (a+b)(a−b)=a^2 − b^2

=( √5+ √2)( √5−√2)

=(√5)^2−(√2)^2

=5−2

=3

Answer 2

Answer:

=> (√5-√2)(√5+√2)

=> using identity: (x-y)(x+y) = (x^2-y^2)

=> (√5)^2-(√2)^2

=> 5-2

=> 3

this is your answer friends.
