I don't believe yours is correct.... it would simplify to : 8√15

I believe I have settled this one. The issue is interpretation-based.

Cphill's interpretation: \(4\sqrt{15}-\textcolor{red}{\frac{10\sqrt{3}}{5}}+3\sqrt{60}\)

ManuelBautista2019: \(4\sqrt{15}-\textcolor{red}{10\sqrt{\frac{3}{5}}}+3\sqrt{60}\)

According to my individual calculation, both of you got the correct answer, assuming your interpretation.
