using the identity (A + B)^3 = A^3 + B^3 + 3A^2B + 3AB^2, U GET (2x+4z)^3 = (2x)^3 + (4z)^3 +3(2x)^2(4z) + 3(2x)(4z)^2 = 8x^3 + 64z^3 + 3(4x^2)(4z) + 3(2x)(16z^2) = 8x^3 + 64z^3 + 48x^2z + 96xz^2 I made a slight mistake in the first one so i am correcting and sending it after this

using the identity (A  B)^3 = A^3  B^3 3A^2B + 3AB^2, U GET (2xy)^3 = (2x)^3  (y)^3 3(2x)^2(y) + 3(2x)(y)^2 = 8x^3  y^3  3(4x^2)(y) + 3(2x)(y^2) = 8x^3  y^3  12x^2y + 6xy^2
