Answer:
4C0(m⁴)(3⁰) + 4C1(m³)(3¹) + 4C2(m²)(3²) + 4C3(m¹)(3³) + 4C4(m⁰3⁴)
Step-by-step explanation:
Using Pascal's triangle, going to the 4th line down, the coefficients are 1, 4, 6, 4 and 1. This is the same as 4C0, 4C1, 4C2, 4C3, and 4C4.
In these expansions, the exponent for the first term of the binomial will start at 4 and decrease, while the exponent for the second term of the binomial will start at 0 and increase.
This gives us
4C0(m⁴)(3⁰) + 4C1(m³)(3¹) + 4C2(m²)(3²) + 4C3(m¹)(3³) + 4C4(m⁰3⁴).
