Solution 1

This statement is incorrect. In matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. Therefore, you can multiply matrix X (which has 2 columns) by matrix Y (which has 2 rows). This operation will result in a new matrix with 3 rows Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
