10t-640/t^2 = 0

Thank you so much for huge help:)))

  • math -

    Assuming the usual carelessness with parentheses, I read this as

    (10t-640)/t^2 = 0

    a fraction is zero if the numerator is zero. So,

    10t-640=0
    t = 64

    Now, if you meant

    10t - (640/t^2) = 0

    then clear the fraction and we have

    10t^3 - 640 = 0
    t^3 = 64
    t = 4

    Thank you so much:)))
