a)
[tex] = | \sqrt{16} - \sqrt{15} | + | - 5| + | \sqrt{15} - \sqrt{9} | \\ = \sqrt{16} - \sqrt{15} + 5 + \sqrt{15} - \sqrt{9} \\ = 4 + 5 - 3 \\ = 6[/tex]
b)
[tex]2 \frac{1}{3} + | \sqrt{9} - \sqrt{6} | + | \sqrt{16} - \sqrt{6} | \\ = 2 \frac{1}{3} + \sqrt{9} - \sqrt{6} + \sqrt{16} - \sqrt{6} \\ = 2 \frac{1}{3} + 3 + 4 \\ = \frac{7}{3} + 7 \\ = \frac{28}{3} [/tex]
c)
[tex] \sqrt{12} - \sqrt{11} + | \sqrt{9} - \sqrt{11} | - | \sqrt{12} - \sqrt{9} | \\ = \sqrt{12} - \sqrt{11} + \sqrt{11} - \sqrt{9} - \sqrt{12} + \sqrt{9} \\ = 0[/tex]
d)
[tex] \sqrt{5} - \sqrt{2} + 6 - \sqrt{5} + \sqrt{2} - 1 \\ = 5[/tex]
