Question 122025
<b><pre>

{{{sqrt(75a^2)/sqrt(5)}}}


{{{5a*sqrt(3)/sqrt(5)}}}


But simplest form demands that you rationalize the denominator, so


{{{(5a*sqrt(3)/sqrt(5))(sqrt(5)/sqrt(5))}}}


{{{5a*sqrt(3)sqrt(5)/5}}}


{{{a*sqrt(15)}}}


Another way to go about it would be:


{{{sqrt(75a^2)/sqrt(5)}}}
{{{sqrt(75a^2/5)}}}
{{{a*sqrt(15)}}}.

Same answer, but tidier
