is the estimator mu=(average(x))^2-((sigma^2)/n)
an unbiased estimator to mu^2 ?

yes, since sigma is known
AND normality has nothing to do with this
why is it unbiased, how did you work it out ?
just one question if I might:
an estimator T is unbiased if E(T)=parameter
where in the solution we calculated E(T) ?
