1 Jawaban

  • 14 (1 + 3^(1/2))(1 - 3^(1/2)) / 3 + 2^(1/2)
    = 14 (1 + 3^(1/2) - 3^(1/2) - 3) / 3 + 2^(1/2)
    = 14 (1 - 3) / 3 + 2^(1/2)
    = 14 (-2) / 3 + 2^(1/2)
    = -28 / 3 + 2^(1/2)
    = -28(3 - 2^(1/2)) / (3 + 2^(1/2))(3 - 2^(1/2))
    = -28(3 - 2^(1/2)) / 9 - 2
    = -28(3 - 2^(1/2) / 7
    = -4(3 - 2^(1/2))
    = -12 - 4 × 2^1/2
    = -12 - 4 akar 2
