10. a) 4²*(√5)²=16*5=80
b)2²*(√6)²=4*6=24
c) (√7)²/3²=7/9
d)
[tex] \frac{ {3}^{2 \times ( \sqrt{8}) {}^{2} } }{ {2}^{2} } = \frac{9 \times 8}{2} = {36} [/tex]
e)
[tex] \frac{ {6}^{2} }{( \sqrt{3} ) {}^{2} } = \frac{36}{3} = 12[/tex]
f)
[tex] \frac{ {3}^{2} }{ {2}^{2} \times ( \sqrt{6} ) {}^{2} } = \frac{9}{4 \times 6} = \frac{9}{24} = \frac{3}{8} [/tex]
