I'm working on a polynomial like (1 + 2x + x² - 3x³ + 7x⁴) raised to a certain power, which could be squared, cubed, or even higher. I need a way to produce a list of the powers and their coefficients after expanding the polynomial. My initial approach was to use for loops and store the results in a dictionary, but I'm now looking into using matrix and vector multiplication because the previous method takes a long time for larger polynomials—like when you have 8 terms raised to the power of 20. Can anyone suggest the most effective way to go about this, especially if matrix multiplication is involved? Thanks in advance!

If JavaScript isn't cutting it for your needs, you might want to reconsider using it at all. JavaScript can be quite slow compared to other languages. You could try using Python with Numpy, which has a pretty handy function called `numpy.polynomial.polynomial.polypow`. It's optimized and might do what you need more efficiently.
True, but keep in mind that Python can have its own speed limitations too. The good thing about Numpy is that it's likely written in C, so it runs faster due to that optimization.
