[tex]a)\\|3-\frac{1}{2}| = |\frac{6}{2} -\frac{1}{2} |= |\frac{6-1}{2} |= |\frac{5}{2} |= \frac{5}{2}[/tex]
[tex]b)\\|-\frac{3}{4}+1| = |\frac{-3}{4}+\frac{4}{4} | = |\frac{-3+4}{4}| = |\frac{1}{4}| = \frac{1}{4}[/tex]
[tex]c)\\|1,15 - 7,5 + 8,85| = |-6,35 + 0,85| = |-5,5,| = 5,5[/tex]
[tex]d)\\|\sqrt{3} +2| = |1,73 + 2| = |3,73| = 3,73[/tex]
[tex]e)\\|\sqrt{5} -\sqrt{2} | = |2,23 -1,41| = |0,82| = 0,82[/tex]
[tex]f)\\|\sqrt{11} -\sqrt{15} | = |3,31 - 3,87| = |-0,55| = 0,55[/tex]
[tex]g)\\|2\sqrt{3} +4| = |2*1,73 + 4| = |3,46 + 4| = |7,46| = 7,46[/tex]
[tex]h)\\|-\sqrt{7} -7| = |-2,64 - 7| =|-9.64| = 9,64[/tex]
[tex]i)\\h)\\|-\sqrt{7} +3| = |-2,64 +3| =|0,35| = 0,35[/tex]
