    Step-by-step explanation:

    first you put the x and apply cube in the ratio

    4:5 = (4x)^3:(5x)^3

    (5x)^3 – (4x)^3 = 61

    125x – 64x = 61

    61x = 61

    x = 61÷61

    x = 1

    4x = 4×1 = 4

    5x = 5×1 = 5

    let prove it and check it is 0 or not –

    (5)^3 – (4)^3 = 61

    125 – 64 = 61

    61 = 61

    =61 – 61

    = 0

    let it is correct
