a= $\sqrt{( \sqrt{3}- \frac{9}{4} )^{2} } - \sqrt{( \sqrt{3}-2) ^{2}} + 0,75$

Answer 1

$a = \sqrt{\Big(\sqrt{3}-\dfrac{9}{4}\Big)^2}-\sqrt{\Big(\sqrt{3}-2\Big)^2}+0,75 \\ \\ a =\Big|\sqrt{3}-\dfrac{9}{4}\Big| - \Big|\sqrt{3}-2\Big|+0,75\\ \\ a =\Big|\sqrt{3}-2,25\Big| - \Big|\sqrt{3}-2\Big|+0,75 \\ \\ a = \Big(2,25-\sqrt3\Big) - \Big(2-\sqrt3\Big) + 0,75 \\ \\ a = 2,25 - \sqrt3 -2+\sqrt3+0,75 \\ \\ a = 0,25+0,75 \\ \\ a = 1$
