i think the formula of a negative exponent is like this:
x^-a = 1/x^a
therefore, the negative just means that it is 1/x^a
and, if there is a negative exponent in the denominator, it means 1/x^-a = 1/1/x^a = x^a
so...
(b^3c^1/a^2)^3
=b^9c^3/a^6

(a^-2 * b^3 / c^-1)^3
with neg exponents you can take the reciprocal to make it a positive exponent, so:
((1/a^2) * b^3 / (1/c))^3 = ((1/a^2)*b^3*c)^3 = ((cb^3)/(a^2))^3
take everything to the 3rd power:
(c^3)(b^9)/(a^6)

You Want It Re-Written? I Guess It Would Be This...
(a^-2*b^3/c^-1)^3 into (1/a^2*b^3/1/c)^3
but solved would be...
b^9/a^6*c^3
I Think...

Try homework helpers websites. It is probably best for you to sit down and spend time with your text book and work through some practice problems each night until you master it. Stay after school and get help from the teacher. Partner up with a classmate who can tutor you. The only way to master mathematics, is to practice, practice, practice.
Give a person an answer and you will do their homework for a day, teach them how to learn and they will learn and be independent & successful for a life time!
