Answer 1

a)$\sqrt{0,04}=\sqrt{\frac{4}{100} } =\frac{2}{10}=\frac{1}{5}=0,2$

b)$\sqrt{1,44}=\sqrt{\frac{144}{100} }=\frac{12}{10}  =\frac{6}{5}  =1,2$

c)$-\sqrt{0,0009}=-\sqrt{\frac{9}{10000} } =-\frac{3}{100}=  -0,03$

d)±$\sqrt{\frac{9}{81} } =$±$\frac{3}{9}=$±$\frac{1}{3}=$±$0,333...$

e)$\sqrt{\frac{49}{4} }=\frac{7}{2}  =3,5$

f)$\sqrt{0,00000016} =\sqrt{\frac{16}{100000000} }=\frac{4}{10000}  = 0,0004$

g)$-\sqrt{4,84}=-\sqrt{\frac{484}{100} } =- \frac{22}{10} =-\frac{11}{5} =-2,2$

h)$\sqrt{0,0484}=\sqrt{\frac{484}{10000} }=\frac{22}{100}  =\frac{11}{50}=  0,22$
