1 Jawaban

  • (4x - 3y)^5
    = (4x - 3y)^2 (4x - 3y)^2 (4x - 3y)
    = (16x^2 - 24xy + 9y^2)(16x^2 - 24xy + 9y^2)
    (4x - 3y)
    = (256x^4 - 384x^3y + 144x^2y^2 - 384x^3y +
    576x^2y^2 - 216xy^3 + 144x^2y^2 - 216xy^3 +
    81y^4)(4x - 3y)
    = (256x^4 -768x^3y + 864x^2y^2 - 432xy^3 +
    81y^4)(4x - 3y)
    = 1024x^5 - 3072x^4y + 3456x^3y^2 - 1728x^2y^3 + 324xy^4 - 768x^4y + 2304x^3y^2
    - 2592x^2y^3 + 1296xy^4 - 243y^5
    = 1024x^5 - 3840x^4y + 5760x^3y^2 - 4320x^2y^3 + 1620xy^4 - 243y^5
