Answer 1

Answer:

we will use identity

a²-b²=a+b a-b

(√6²-√3²)

=6+3

=9 answer

Answer 2

Answer:

(√6+√3)(√6-√3)​

Step-by-step explanation:

$(\sqrt{6} + \sqrt{3} )(\sqrt{6} - \sqrt{3})\\ = (\sqrt{6}) ^{2} - (\sqrt{3}) ^{2} \\(\sqrt{6} + \sqrt{3} )(\sqrt{6} - \sqrt{3}) = 6 - 3 = 3$

Used Formula

(A + B)(A - B) = A^2 -B^2
