@satellite73

OpenStudy (anonymous):

\[3\sqrt{5a}*2\sqrt{25a^{2}}=3\sqrt{5a}*2*5a\] can u now simplify it??

OpenStudy (anonymous):

\[5\sqrt{125a^3}\] ??

OpenStudy (anonymous):

no it can be read as \[3*2*5a*\sqrt{5a}=30a \sqrt{5a}\]

OpenStudy (anonymous):

ohh i see. can you help with some more?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

but you should try to learn the logic

OpenStudy (anonymous):

\[\sqrt{\frac{ 80w^3 }{ 9 }}\]

OpenStudy (anonymous):

\[\sqrt{\frac{ 80w ^{2} }{ 9 }}=\sqrt{\frac{ 2^{2}*2^{2}*5*w ^{2} }{ 3^{2} }}=\frac{ 2*2*w*\sqrt{5} }{ 3 }\]

OpenStudy (anonymous):

\[=\frac{ 4w \sqrt{5} }{ 3 }\]

OpenStudy (anonymous):

thanks:)
