Answer 9

hint:
64=8*8
144=12*12
so:
\[\sqrt {\frac{{64}}{{144}}} = ...?\]

Answer 10

when i divided 64 by 144 i got 0.44444444444444444444444444444444

Answer 11

hint:
\[\sqrt {\frac{{64}}{{144}}} = \pm \sqrt {\frac{{{8^2}}}{{{{12}^2}}}} = ...?\]

Answer 12

\[\frac{ 4 }{ 9 } and -\frac{ 4 }{ 9 } \]

Answer 13

no, since:
\[\begin{gathered}
\sqrt {64} = \pm 8 \hfill \\
\sqrt {144} = \pm 12 \hfill \\
\end{gathered} \]

Answer 14

when i divided 64 by 144 i got 0.44444444444444444444444444444444.
so i went through each answer choice and divided the numerator by the denominator. When i divided 4 by 9 i got "0.44444444444444444444444444444444." so wouldn't that mean that 4 over 9 and negative 4 over 9 is the answer?
