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 \( \frac{-8z^8}{9z^2} \)?
| -\(\frac{8}{9}\)z\(\frac{1}{4}\) | |
| -\(\frac{8}{9}\)z6 | |
| -1\(\frac{1}{8}\)z10 | |
| -\(\frac{8}{9}\)z-6 |
