Here is what i done for the first one

3root125 - 10 1/3root(64^2)

5- 160

= -155

The answer from the key is -11. ^^;;; stuck..

Evaluate a=1 b=2 c=3

1. (a^-2 b^-4) (a^2 b^-5)

2. a^-1 b^3 c^-2/abc

For the evaluates i turned all the negative exponents into positive fractions. After that i multipled/divde all the numbers and got some werid numbers..

answer key for #1 is -1/512 #2 4/27

Also when you getting rid of the negative exponent for e.g:

-2^-1/2 becomes 1/ 2or -2 ^ 1/2 does the base stays negative or it changes into positive with the exponent?

Thank You
