Question

64 × 54 = ?

• A. 3564
• B. 3546
• C. 3654
• D. 3456

Answer 1

Answer:

D. 3456

• • 64 × 54 can be seen as 64 × (50 + 4).

  • This expands to (64 × 50) + (64 × 4).

  • Calculate 64 × 50 = 3200 (64 × 5 = 320, then add a zero).

  • Calculate 64 × 4 = 256.

  • Add these two results: 3200 + 256 = 3456.
