    \[\sqrt{8} = \sqrt{4}*\sqrt{2}\] \[\sqrt{16a^{2}} = \sqrt{16}*\sqrt{a^{2}}\] that should help

    \[\sqrt{16} = \sqrt{4^{2}} = 4\] so for any number \[\sqrt{a^{2}} = a\]

    you want someone to answer your problem? find the square root of 14 of a^2 and sqrt(4)*sqrt(2)

    \[\frac{\sqrt{8} a^{2}}{\sqrt{16a^{2}}} = \frac{\sqrt{4}\sqrt{2}a^{2}}{\sqrt{16}\sqrt{a^{2}}} = \frac{2\sqrt{2}a^{2}}{4a}\]
