Answer 1

Hey !
Here is your answer !!
__________________

▶▶( 3√3 + 2 ) ( 3√3 - 2 )

Using the formula
( a + b ) ( a - b ) = a2 - b2

So ( 3√3)2 - (2)2

▶ ( 9 × 3 ) - (4)


▶ 27 - 4


▶ 23 ( Answer )
______________

Hope it helps !!

Answer 2

hey
#ur Ans
_________

Given that

(3√3 +2) (3√3 -2)

so


apply the formula

${a}^{2} - {b}^{2} = (a + b)(a - b) \\ \\ now \\ \\ = > (3 \sqrt{3} {)}^{2} - {2}^{2} \\ \\ = > 9 \times 3 - 4 \\ \\ = > 27 - 4 \\ \\ = > 23 \: ans$
