Simplify. remember to write the powers as a positive number. a^−2*b^5

b^5 divided by a^2

I don't know how to do the fraction thingy on this thing but to explain it, since a has a negative exponent it has to move to the denominator for this equation to work. That is why the b^2 is on top and the a^2 on the bottone. Once the a^-2 goes to the bottom, it loses the negative sign.  

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

i think the answer is d im not sure
