Answer:

14. -5√30 +3√2

15. 18√5 -30√3

Step-by-step explanation:

You can multiply radicals using ...

(√a)(√b) = √(ab)

And you can simplify radicals using ...

√(a²b) = a√b

_____

14. Using the distributive property, then simplifying the radicals, we have ...

$\sqrt{3}(-5\sqrt{10}+\sqrt{6})\\\\=-5\sqrt{3\cdot10}+\sqrt{3\cdot6}\\\\=-5\sqrt{30}+\sqrt{3^2\cdot2}\\\\=\boxed{-5\sqrt{30}+3\sqrt{2}}$

__

15. Similarly, ...

$-2\sqrt{15}(-3\sqrt{3}+3\sqrt{5})\\\\=6\sqrt{15\cdot3}-6\sqrt{15\cdot5}\\\\=6\sqrt{3^2\cdot5}-6\sqrt{5^2\cdot3}\\\\=\boxed{18\sqrt{5}-30\sqrt{3}}$
