**Steve**, Wednesday, April 9, 2014 at 11:34amAssuming 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
