Just need some help...
Directions:
Multiply or raise to the power as indicated... Then simplify the result. Assume all variables represent positive numbers.
1. 5(square root of 6) times twothirds(square root of 15)= 3 onethird (square root of 90)= (This is where i am stuck...) 3 onethird (square root of 9) (Square root of 5) (Square root of 2) which would = 9.9 (square root of 5) (Square root of 2)
2. 4 square root of a times 3 square root of a= You would get 12, but what do you do to the a's... Thanks!!!

1. What do you want to get for this question?
2.12a 
Miltiply whole numbers and roots separately. So 3 one third of 90 means 10/3 root 90 and 5 root of 6 * 2/3 root 15 becomes 10/3 root 90. Therefore 10/3 root 90=10/3 root 90. Which will be 1=1 after dividing both sides by 10/3 root 90.
