Question

(1/2)(1/2) + (root3/2)(root3/2)

Answer 1

$\bigg( \dfrac{1}{2} \bigg)\bigg( \dfrac{1}{2} \bigg) + \bigg( \sqrt{ \dfrac{3}{2} } \bigg)\bigg( \sqrt{ \dfrac{3}{2} } \bigg)$

$= \bigg( \dfrac{1}{2} \bigg) {}^{2} + \bigg( \sqrt{\dfrac{ 3 }{2}} \bigg){}^{2}$

$= \frac{1}{4} + \frac{3}{4}$

$= \frac{1 + 3}{4}$

$= \frac{4}{4}$

$= 1$
