Question

find the value of
$(2 + \sqrt{3)} (2 - \sqrt{3} )$
​

Answer 1

$\sf(2 + \sqrt{3)} (2 - \sqrt{3} ) \\ \sf {2}^{2} - {( \sqrt{3}) }^{2} \\ \sf 4 - 3 \\ \boxed{1}$

Answer 2

Solution :

$\implies \: (2 + \sqrt{3)} (2 - \sqrt{3} )</p><p>$

$\implies \: 2^2 \: - (\sqrt{3})^2</p><p>$

$\implies \: 4 - 3$

$\implies \: 1 \:$ ✯
