And
(3+√3)(3-√3)=?

Answer 1

$\Huge{\color{skyblue}{\fbox{\textsf{\textbf{♪Solution♪:-}}}}}$

$\color{red}\mathtt(3+√3)+ (3-√3)$

$\color{blue} = 3 + \sqrt{3} + 3 - \sqrt{3}$

$\color{green} = 3 + 3$

${\boxed {\bold {\color{black} = 6}}}$

$\huge \bold{ \mathfrak{ \underline{And}}}$

$\mathtt\color{red}(3+√3)(3-√3)$

$\color{blue} = {3}^{2} - { \sqrt{3} }^{2}$

$\color{green} = 9 - 3$

$\boxed {\bold\color{purple} = 6}$

FORMULA USED :—

$\small {\boxed{ \bold{(a + b)(a - b) = {a}^{2} + {b}^{2}}}}$
