Answer:
[tex]6. \: \sqrt{121} = \green{ \boxed{11}}[/tex]
[tex]7. \: - \sqrt{0.49} = \green{ \boxed{ - 0.7}}[/tex]
[tex]8. \: \sqrt{ \frac{81}{64} } = \green{ \boxed{ \frac{9}{8} }}[/tex]
[tex]9. \: - \sqrt{0.0016} = \green{ \boxed{ - 0.04}}[/tex]
[tex]10. \: \sqrt{ \frac{18}{21} } = \sqrt{ \frac{9 \times 3}{21} } = 3 \sqrt{ \frac{3}{21} } = \green{ \boxed{3 \sqrt{ \frac{1}{7} } }}[/tex]
