Question

(3 + √3 ) ( 3 −√3) on simplification becomes equal to

Answer 1

given★

• (3 + √3 ) ( 3 −√3)

solution★

• $\implies \: (3 + \sqrt{3} )(3 - \sqrt{3} )$

• we know that

$\implies \: (a + b)(a - b) = a {}^{2} - b {}^{2}$

• when a=3 and b =√3

• $\implies \: (3 {}^{2} - ( \sqrt{3 {}^{} } ) {}^{2} )$

• $\implies \: 9 - 3$

• $\implies \: 6$
