Multiplying 3x² by 4x³ results in 12x⁵ since we multiply the coefficients 3 and 4, and add the exponents x² and x³. Similarly, multiplying 3x² by -2x² gives us -6x⁴, as we multiply -2 and 3, and add the exponents x² and x². Mar 19, 2021 · Jordan bought 2 slices of cheese pizza and 4 sodas for $8.50.
