    if 2p² = 3q² = 4r² = 24s²
    prove that 1/p + 1/q + 1/r - 1/s = 0

    Kena buat persamaan serentak la ni..

    1/p + 1/q + 1/r - 1/s = 0
    2p² - 3q² - 4r² - 24s² = 0

    1/p + 1/q + 1/r - 1/s = 2p² - 3q² - 4r² - 24s²

    Pening aku..

    ke guna kaedah persamaan Gauss?? kaedah persamaan gauss Jordan??


    superior mane ade 2p² laaaaa
    maksud aku
    two power of p = three power of q = four power of r = 24 power of s

    ex. 9³ = [ 9 digantikan dengan 2 n 3 digantikan dengan p ]

    aku ambil kat2 1/2jam bru dapat jawaban

    g(x) = 4x+3

    gf(x) = ?

    Solution:

    gf(x)= 4(2x-1) + 3
    = 8x - 4 + 3
    = 8x - 1

    fg(x)= 2(4x+3) - 1
    = 8x + 6 - 1
    = 8x + 5

    laaaaa knp nie soalan hamba blum terjawab dah ade soalan laen
    kan dah cakap ade jawapan hummmmm
    korang cepat putus asa laaaa.....
    jawaban nie aku cari sendri tau
    ok nie jawaban die.....

    soalan:
    [po] = power of
    2[po]p = 3[po]q = 4[po]r = 24[po]s
    prove,
    1/p + 1/q + 1/r - 1/s = 0

    jawaban nye:
    2[po]p = 2[po](2r)
    p = 2r
    (2[po]p)(3[po]q) = (24[po]s)(24[po]s)
    = [2[po](6s)][3[po](2s)]
    p = 6s
    q = 2s
    skrang ado 3 equation
    p = 2r
    p = 6s
    q = 2s
    (3)(q) = (3)(2s)
    3q = 6s
    then,
    p = 2r = 6s = 3q
    if, p = 6s
    p/6 = s
    6/p = 1/s

    2r = p
    r = p/2
    1/r = 2/p

    3q = p
    q = p/3
    1/q = 3/p

    disebabkan, 6/p = 1/s
    maka....

    1/p + 3/p + 2/p = 1/s
    3/p = 1/q
    2/p = 1/r
    thus,
    1/p + 1/q + 1/r = 1/s
    siap....

    Wehh.. cakap dlm BM boleh tak??? Aku blaja add math dgn nama2 bab guna BM, thn2002-2003. Ntah bab mana tah ko maksudkan tu yang atas2 tu..

    [power of] = po. Dlm BM kitorg pakai apa dulu?? aku masih blur2 kalau power of yg dimaksudkan tu bukan "²". Abis tu apa? Boleh tak pakai simbol2 yg btul2 dlm math? aku tak penah belaja guna [po] ni... masuk la character map pd accessories tu.. guna simbol yg sewajarnya k..
