Question

simplyfy the given thing​

Answer 1

Answer:

(3+√3) (3-√3)

using the formula (a+b)(a-b) =a^2-b^2

here a=3 and b=√3

(3)^2-(√3)^2

9-3=6

(√5-√2)(√5+√2)

using the formula same formula mentioned above

a=√5 and b=√2

5-2=3

Answer 2

Answer:

Step-by-step explanation:

the given sum is in the form of indentity (a-b)(a+b) = (a^2-b^2)

root and square will be eliminated,

so , it can be written as $(\sqrt{5} )^2 - (\sqrt{2})^2 \\\\\\5-2 = 3$
