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 \( \frac{1z^5}{7z^4} \)?
| \(\frac{1}{7}\)z-1 | |
| \(\frac{1}{7}\)z\(\frac{4}{5}\) | |
| \(\frac{1}{7}\)z | |
| 7z9 |
