Statistical Inference — UMVUE of theta to the r for a power-function density

Let X1,X2,X3,...,XnX_1, X_2, X_3, ..., X_n be independently and identically distributed random variables with f(x,θ)=3x2θ3f(x,\theta)=\frac{3x^2}{\theta^3}; 0<x<θ0<x<\theta; 00 otherwise. The UMVUE of θr\theta^r is given by
