Answer:

Remember that in the transpose matrix of the matrix A, the entry a_{ij} of A will be the entry a_{ji} of A^T.

Then if

B=\left[\begin{array}{ccc}-1&1&-3\\0&2&3\end{array}\right], B^T=\left[\begin{array}{ccc}-1&0\\1&2\\-3&3\end{array}\right]

Then

B^TB=\left[\begin{array}{ccc}1&-1&3\\-1&5&3\\3&3&18\end{array}\right]
