Question

1. which of these expressions is the same as 4×3×4?

a. 7×7
b. 8×3
c. 4×7
d. 12×4

Explanation:

Step1: Calculate \(4\times3\times4\)

First, multiply \(4\times3 = 12\), then multiply \(12\times4\), so \(4\times3\times4=12\times4\).

Step2: Analyze each option

• Option A: \(7\times7 = 49\), while \(4\times3\times4 = 48\), not equal.
• Option B: \(8\times3 = 24\), not equal to \(48\).
• Option C: \(4\times7 = 28\), not equal to \(48\).
• Option D: \(12\times4 = 48\), which is equal to \(4\times3\times4\).

Answer:

D. \(12\times4\)
