$sqrt(5a)*sqrt(15a)$ can be also changed to this form $sqrt(5a*15a)$

Now, we have all under one $sqrt$ . We can multiply $5a$ with $15a$ , which gives us $75a^2$
We put this under $sqrt$ and we get $sqrt(75a^2)$

This can be changed into

$8.660254a^2$ $=>$ $5sqrt(3)*a^2$

How do you simplify sqrt(5a) * sqrt(15a)sqrt(5a) * sqrt(15a)?
