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 two-thirds(square root of 15)= 3 one-third (square root of 90)= (This is where i am stuck...) 3 one-third (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!!!

    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.
