Question: 5. 4 x 8 =\nBreak apart 8 into 5 + 3.\n\n____ x 5 = ____\n____ x 3 = ____\n____ + ____ = ____
1. The problem is to calculate $4 \times 8$ by breaking apart $8$ into $5 + 3$.\n\n2. We use the distributive property of multiplication over addition: $$a \times (b + c) = a \times b + a \times c$$\n\n3. Applying this to our problem: $$4 \times 8 = 4 \times (5 + 3) = 4 \times 5 + 4 \times 3$$\n\n4. Calculate each part:\n- $4 \times 5 = 20$\n- $4 \times 3 = 12$\n\n5. Add the results: $$20 + 12 = 32$$\n\n6. Therefore, $$4 \times 8 = 32$$
