Use the matrix multiplication pattern:

(batch, input_features) x (input_features, output_features)

DL-C01-C-006

Check only the inner dimensions. They must match.

DL-C01-C-007

Align the names with the numbers: (batch, positions, features) and (3, 7, 16).

DL-C01-C-008

Compare the total number of entries in each shape.

DL-C01-C-009

The bias has one value per feature and is reused for every example.

DL-C01-C-010

Use the order given in the question: (input_features, output_features).
