Question

Can i get some help? (radicals)

Answer 1

\(\bf \sqrt{12}\cdot (-1+\sqrt{5})\implies \sqrt{12}\cdot (-1)+\sqrt{12}\cdot \sqrt{5}\implies -\sqrt{12}+\sqrt{12\cdot 5}\\ \quad \\
-\sqrt{12}+\sqrt{60}\\ \quad \\
\color{green}{60 = 2\cdot 2\cdot 3\cdot 5\implies 2^2\cdot 3\cdot 5\\ \quad \\
12 = 2\cdot 2\cdot 3\implies 2^2\cdot 3}\\ \quad \\
-\sqrt{12}+\sqrt{60}\implies -\sqrt{2^2\cdot 3}+\sqrt{2^2\cdot 3\cdot 5}\)
