1. What is the value of (0.1)^4 ?
A. 0.0004 B. 0.0001 C. 0.1 D. 0.4I think it's B.
2. Which number is equivalent to 1/6^2 ?A. 2^6 B. 6^2 C. -6^2 D. 6^-2I'm not sure about this one.
3. Which expression is equivalent to 5^3 x 5^2 x 5^6 ?
A. 5^11 B. 5^36 C. 125^11 D. 125^36I think it's B.
4. Which expresion is equivalent to 10^9/10^3 ?
A. 10^3 B. 10^6 C. 10^12 D. 10^27I think this one is B also.
6. Which expression has the same value as (6462)3?
A. 6^2 B. 6^5 C. 6^6 D. 6^10
I think it's C.
7. Which expression has the same value as this one? (0.5^3 x 0.2^5)^6 ?
A. 0.1^14 B. 0.1^48 C. 0.5^9 x 0.2^11 D. 0.5^18 x 0.2^30
I think its B.
PLEASE help 
Thank you.

1. Think of 0.1*0.1*0.1*0.1 in fraction form: 1/10*1/10*1/10*1/10 = 1/10,000 = 0.0001. Correct.
2. 1/ (6^2) --> Remember, you can move 6^2 to the numerator if you change the sign of the exponent from positive to negative.
3. Add the exponents together. It is not B.
4. Subtract the exponents to get a number, #; then 10^# will be your answer. Yes, it is B.
6. Subtract the exponents for number 4 just like you did for number 4 and multiply by the new exponent 3. C is correct.
7. You can separately multiply the two terms: All you have to do is multiply the exponents by 6 and that's it keeping the X in the middle.
