Compute the product AB by the definition of the product of matrices, where Ab, and Abz are computed separately, and by the row-column rule for computing AB. A= 1 Set up the product Ab,, where b, is the first column of B. Ab, -O (Use one answer box for A and use the other answer box for b, .) Calculate Ab, where b, is the first column of B. Ab, -O (Type an integer or decimal for each matrix element.) Set up the product Ab,. where b, is the second column of B. Ab, =O (Use one answer box for A and use the other answer box for bz.) Calculate Abz, where by is the second column of B. Ab, -O (Type an integer or decimal for each matrix element.) Determine the numerical expression for the first entry in the first column of AB using the row-column rule. Choose the correct answer below.
