Question

(2) (3 +√3) (3-√3) simplify following expression​

Answer 1

Answer:

if we see we can use the property (a-b) (a+b)=(a-b)²

=2(3²-√3²)

=2(9-9)

=2(0)

=0

so the answer is 0

Answer 2

Answer:

• 6 is answer.

Solution:

Using identity,

We know that,

$\red\bigstar\;\boxed{(a+b)(a-b)=a^2-b^2}$

Appling this identity here,

$\implies (3+\sqrt{3})(3-\sqrt{3})\\\\\implies (3^2-\sqrt{3}^2)\\\\\implies 9-3\\\\::\implies 6$
