    Resolved [RESOLVED] Perfect cube???

    Expressed as the product of prime factors


    540 = 2^2 x 3^2 x 5 and 72 = 2^3 x 3^2


    Use these results to find

    the smallest integer, t, such that 540t is a perfect cube.


    I have looked through the working solutions but I don't understand the steps on why it is been done in that way. Can anyone explain it to me or maybe you could do it in another way so that I can understand it better? Thanks a lot.


    Working solutions:

    540t = 2^2 x 3^2 x 5 x (2x5^2)
    => t = 2 x 5^2
    t = 50


    Please answer this thread asap. Thanks a lot.
