Calculate the values ​​of the numbers below, for each individual case:
a) x = [tex]\sqrt{(\sqrt{12}-4)^{2} } - \sqrt{(\sqrt{27}-6)^{2} } - \sqrt{(\sqrt{48}-7)^{2} } +\sqrt{(\sqrt{75}-9)^{2} }[/tex]
b) x = [tex]\sqrt{(\sqrt{7}-3)^{2} } + \sqrt{(\sqrt{5}-4)^{2} } + \sqrt{(2-\sqrt{5})^{2} } + \sqrt{(1-\sqrt{7})^{2} }[/tex]
