sqrt2a+9sqrt8a^3 I cant figure this one out

OpenStudy (anonymous):

\[9 \sqrt{8 a^3}+\sqrt{2 a}\] this?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

\[9 \left(8 a^3\right)^{\frac{1}{2}}+(2 a)^{\frac{1}{2}}\]

OpenStudy (anonymous):

\[\sqrt{8a^3}=\sqrt{4a^2\times 2a}=\sqrt{4a^2}\times \sqrt{2a}=2a\sqrt{2a}\]

OpenStudy (anonymous):

\[9\sqrt{8a^3}+\sqrt{2a}=9\times2a\sqrt{2a}+\sqrt{20}=18a\sqrt{2a}+\sqrt{2a}=(18a+1)\sqrt{2a}\]
