radical expressions

Need help solving these problems

-√3/7
(4√12)(3√20)
√2+√8+√50

1. i don't understand your first expression: $-\sqrt {\frac37}$ or $-\frac {\sqrt 3}{7}$

2. $(4sqrt12)(3sqrt20) = (4*3)(sqrt{12*20}) = 12sqrt{240}$ Can simplify from here?

3. $sqrt2 + sqrt8 + sqrt{50}=sqrt2 + 2sqrt2 + 5sqrt2$ Can simplify from here?
