Studdy Solution
STEP 1
1. A is a 3x2 matrix and B is a 2x2 matrix.
2. The product AB is given partially, with some missing entries.
3. Matrix multiplication rules apply.
STEP 2
1. Verify if matrix multiplication is possible.
2. Calculate the product AB.
3. Compare the calculated result with the given partial result.
4. Fill in the missing entries if possible.
STEP 3
To multiply matrices A and B, the number of columns in A must equal the number of rows in B. A is a 3x2 matrix and B is a 2x2 matrix. A has 2 columns and B has 2 rows, so multiplication is possible.
STEP 4
Let's calculate AB:
Calculating each element:
Therefore,
STEP 5
Now, let's compare our calculated result with the given partial result:
Calculated:
Given:
We can see that the entries that are given match our calculated results.
STEP 6
We can now fill in the missing entries:
Therefore, the complete product AB is:
