    Dear Sir! I have no idea in maths, but it doesn’t trouble me to see and admire your love, your deep understanding of logics of the science you choose. Greetings from Russia.

    Take log on both sides we get x=log 24 to base 4

    2²ˣ = 2³3
    2²ˣ⁻³ = 3
    2x - 3 = log₂3
    x = (3 + log₂3)/2

    2xlog2=3log2+log3
    x=1.5+log3/2log2

    4^x = 2^(2x) = 24 = 3(2^3)
    2^(2x - 3) = 3
    (2x - 3) = (log3)/(log2)
    2x = 3 + (log3)/(log2)
    x = 3/2 + (log3)/(2log2)

    Whywe can juste apply Ln at the beginning?

    Make the task more difficult. For example, the number 23 instead of 24.

    x=log24/log4=log(2³×3)/log2²=(3log2+log3)/2log2≈(3×0.301+0.477)/(2×0.301)≈1.38/0.602≈2.2924.
    Deviation is about 0.0001.

    Germany, Math Olympiad: 4ˣ = 24; x =?
    4ˣ = 24 = 4(6), 4ˣ⁻¹ = 6 = 2(3), x - 1 = log₄6 = log₄2 + log₄3 = (log₂2 + log₂3)/2
    x = 1 + log₄6 = (log₂2 + log₂3)/2 = 1 + 1/2 + 0.793 = 2.293
    Answer check:
    x = 2.293: 4ˣ = 4²·²⁹³ = 24; Confirmed
    The calculation was achieved on a smartphone with a standard calculator app
    Final answer:
    x = 1 + log₄6 = 2.293

    I brute forced it in my calculator and got 2.2924812505. it's the value of the x when calculated 😆
