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 \( \frac{9a^5}{7a^2} \)?
| \(\frac{7}{9}\)a3 | |
| 1\(\frac{2}{7}\)a3 | |
| \(\frac{7}{9}\)a7 | |
| 1\(\frac{2}{7}\)a-3 |
