a.
[tex] \frac{ \frac{3}{5} + \frac{7}{5} }{ 2} = \frac{ \frac{10}{5} }{2} = \frac{2}{2} = 1[/tex]
b.
[tex] \frac{6 \sqrt{6} + 8 \sqrt{6} }{2} = \frac{14 \sqrt{6} }{2 } = 7 \sqrt{6} [/tex]
2)
a.
[tex] \sqrt{25 \times 36} = 5 \times 6 = 30 [/tex]
b.
[tex] \sqrt{2 \sqrt{6} \times 3 \sqrt{6} } = \sqrt{6 \times 6} = \sqrt{36} = 6[/tex]
