To multiply terms with the same base, multiply the coefficients and add the exponents. To divide terms with the same base, divide the coefficients and subtract the exponents. For example, 3x2 x 2x2 = 6x4 and \({8x^5 \over 4x^2} \) = 2x(5-2) = 2x3.
What is \( \frac{-9c^5}{2c^2} \)?
| -4\(\frac{1}{2}\)c10 | |
| -4\(\frac{1}{2}\)c3 | |
| -\(\frac{2}{9}\)c3 | |
| -\(\frac{2}{9}\)c-3 |
