a)
[tex] \sqrt{25 \times 121 \times 4} = \sqrt{25} \times \sqrt{121} \times \sqrt{4} = 5 \times 11 \times 2 = 110[/tex]
b)
[tex] \sqrt{ \frac{9}{16} } \times \sqrt{ \frac{4}{81} } = \frac{3}{4} \times \frac{2}{9} = \frac{1}{6} [/tex]
c)
[tex] \sqrt{16 + 9} = \sqrt{25} = 5[/tex]
d)
[tex] \sqrt{8} \times \sqrt{18} = \sqrt{144} = 12[/tex]
e)
[tex] \sqrt{169 - 144} = \sqrt{25} = 5[/tex]
f)
[tex] \sqrt{ \frac{8}{5} } \times \sqrt{ \frac{125}{2} } = \sqrt{ \frac{8}{5} \times \frac{125}{2} } = \sqrt{100} = 10[/tex]
