Simplify the square root of of the fifth root of 64q^8v^6 or (√^5√64q^8v^6).

I see no way to simplify anything.
"square root of of the fifth root" is the 10th root.
Since none of the factors are above the 10th power, all you can say is
tenthroot (64q^8v^6) 
1. Simplify the expression. ¡Ì625
2. Evaluate the expression for a = ¨C1 and b = 5.
