5. A random sample of size n is taken from a distribution with pdf:

f(x;θ) = θx^(θ-1 ) 0 < x < 1; θ > 0.

Find the maximum likelihood estimator of θ.

I tried teaching myself out of the book but it has no examples. Can someone run me through a step by step way of solving this? I have nothing to reference and my notes have 2 lines on it.
