Question

simplify
$(3 + \sqrt{3)} (3 - \sqrt{3)}$

Answer 1

Hey,


(3+√3) (3-√3)

This is in the form of (a+b) (a-b)

we can write it as a² -b²

(3+√3) (3-√3)

(3)² - (√3)²

9 - 3

6

Therefore (3+√3) (3-√3) = 6

HOPE IT HELPS YOU:-))

Answer 2

$\Huge{\boxed{\boxed{Answer:}}}$

$\boxed{identity = (x + y)(x - y) = {x}^{2} - {y}^{2} }$

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


$\huge{ \boxed{ \therefore (3 + \sqrt{3} )(3 - \sqrt{3} ) = 6}}$
