Question: 3 b^-2 c/ a^0(4 bc^2/ z^2 - 3 a^-2/ c^-3) 3 b^-2 c over or divided by a^0 (4 bc^2 over z^2 subtract 3 a^-2 over c^-3) Expand:3 b^-2 c/ a^0(4 bc^2/ z^2 - 3 a^-2/ c^-3)?

## Best Answers: 3 b^-2 c/ a^0(4 bc^2/ z^2 - 3 a^-2/ c^-3)?

This is a pretty tedious problem, but here's some info to help you get started... just in case you don't get any answers that are better than people telling you they don't know how to do it or that you should do your own homework: The best way to handle a number or variable that has a negative exponent is to move it to the other side of the fraction bar and make it positive. When a number or variable (except 0) has 0 as an exponent, the whole thing is equal to 1. When you need to add or subtract fractions, put them over a common denominator. For example, if the denominators were z^2 and a^2, the common denominator would be a^2z^2. Good luck!
