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 \( \frac{-4y^7}{9y^3} \)?
| -2\(\frac{1}{4}\)y10 | |
| -2\(\frac{1}{4}\)y4 | |
| -2\(\frac{1}{4}\)y-4 | |
| -\(\frac{4}{9}\)y4 |
