1. (.01)^-3/2 = 1/((0.01)^3/2) = 1/((sqrt(0.01))^3) = 1/(0.1^3) = 1/0.001 = 1,000
2. (9/49)^3/2 = (sqrt(9/49))^3 = (3/7)^3 = (3^3)/(7^3) = 27/343
3. (x^2 - 5x +12)^1/5 = 2^3/5 so x^2-5x+12 = 2^3 = 8 so x^2-5x+4 = 0 = (x-4)(x-1) therefore x = 4 or 1, either answer should work.
4. (x-6)^1/3 = I don't understand what this is asking...
5. 16^-1/4 = 1/(16^1/4)= 1/2 = 0.5

Here's a start for you...
