a) [tex]\sqrt[]{25*121*4} = \sqrt[]{25}*\sqrt[]{121} * \sqrt[]{4} = 5 * 11 * 2 = 10 * 11 = 110\\[/tex]
b) [tex]\sqrt{ \frac{9}{16} * \frac{4}{81}} = \frac{\sqrt{9} }{\sqrt{16} } * \frac{\sqrt{4} }{\sqrt{81} } = \frac{3}{4} * \frac{2}{9} = \frac{1}{2} * \frac{1}{3} = \frac{1}{6}[/tex]
c) [tex]\sqrt{25} =5[/tex]
d) [tex]\sqrt{144} = 12[/tex]
e) [tex]\sqrt{25} = 5[/tex]
f) [tex]\sqrt{\frac{8*125}{5*2} } = \sqrt{\frac{1000}{10} } = \sqrt{100} = 10[/tex]
