    Nachukia sana hesabu, lakini ukifanya hivyo unapata 0 both sides, and not 4

    2^x =4x......log
    log2 ^x=log4x.
    Xlog2=log(2^2)X.
    Xlog2=log(2^2)+logX.
    Xlog2=2log2+logX
    logX=Xlog2-2log2
    logX=(X-2)Log2
    X=(X-2)2
    X=2X-4
    4=2X-X
    X=4.

    Heshima mkuu. lakini kwenye red hiyo sheria ni ipi hiyo!!. hiyo Log jinsi ilivyopotea hapo!!.

    maana nilitegemea iwe:

    LogX=(X-2)Log2
    X=2[SUP](X-2)[/SUP] then uendelee kutoka hapo.

    Hiyo sheria uliyotumia hapo juu, naomba ifafanue zaidi.

    Sio ugomvi kaka, tuelimishane tu. kuwa log base 10 sidhani kama ni ishu, hata kama ingekuwa base 2 as long both logs on both sides have the same base.

    kwa jinsi ninavyoona hapo hizo log umezicancel hapo kama number, kitu ambacho sidhani kama ni sahihi kwenye sheria za log. ndio mana nikaomba, kifupi sijawahi kuona hiyo kitu.

    kama una uwezo zaidi wa kunieleza hiyo sheria nitashukuru. sidhani kama kwenye vitabu ipo.
