So I'm given a matrix A that is already in RREF and I'm supposed to find the null space of its transpose.(adsbygoogle = window.adsbygoogle || []).push({});

So I transpose it. Do I RREF the transpose of it? Because if I transpose a matrix that's already in RREF, it's no longer in RREF. But if I RREF the transpose, it gives me a matrix with 2 leading entries that are both equal to zero. I don't think I'm doing it right.

Thanks.
