STEPS~

1.ok so the first thing that you want to do is to get rid of the square root in the denominator.To do this you want to multiply the fraction by something that won't change like 1. So we are going to multiply it by (square root) 5a over (square root) 5a,because something divided by itself equals 1.

EX.

(square root)30a^5 (square root)5a

_________________ * ______________

(square root)5a (square root)5a

2. Then you would use your distributive property to multiply the things together. So you would multiply (30a^5)(5a)

which equals (square root) 150a^6

THEN you would do the samething to the bottom

which equals (square root) 25a^2

EX.

(square root)150a^6

__________________

(square root)25a^2

3. so then you would take the things that you have two of out.You do this by factoring each of the numbers.P.S. on the bottom since you multipied it by itself you will always have two of each eliminating the square root and leaving you with the same thing you started out with 5a without the square root

EX.

(square root)2*3*5*5*a*a*a*a*a*a

_______________________________

(square root) 5*5*a*a

4.Then you take out the groups of two whcih leaves one. Meaning you take out a two fives you just have one 5 on the outside of the square root.

EX.

5a^3(square root)2*3

_____________________

5a

5. uliminate (divide out/simplify)

EX.

5*a*a*a(square root)6

____________________

5*a

6. The 5a cancels itself out leaving you with

a^2(square root)6

AND THATS YOUR ANSWER

i hope that helped, do you understand???
