Can anyone help me with simplifying four radical expressions for Algebra 1B?? I will give medal to best answer, and become a fan to anyone that helps!

1. sqrt 64y^10h^5/sqrt 16 y^12h^3
a) sqrt 4h^2/sqrt y^2
b) 2h/y
c)2 sqrt h^2/sqrt y^2
d) 2hy

2. sqrt 7+3 sqrt 7
a)2 sqrt 7
b)4 sqrt 14
c)4 sqrt 7
d)2 sqrt 14

3. 2 sqrt 6+3 sqrt 96
a)14 sqrt 6
b)12 sqrt 96
c)5 sqrt 96
d)50 sqrt 6

4. (3+sqrt 6)(3-sqrt 6)
a)-27
b)3
c)9+6
d)15+6 sqrt 6
