Question

which of the following expressions is not the same as
a. $6 \times 6 \times 5$
b. $1 \times 12 \times 5$
c. $2 \times 6 \times 5$
d. $3 \times 4 \times 5$

Explanation:

Step1: Calculate A's value

Calculate \( 6\times6\times5 \). \( 6\times6 = 36 \), then \( 36\times5 = 180 \).

Step2: Calculate B's value

Calculate \( 1\times12\times5 \). \( 1\times12 = 12 \), then \( 12\times5 = 60 \).

Step3: Calculate C's value

Calculate \( 2\times6\times5 \). \( 2\times6 = 12 \), then \( 12\times5 = 60 \).

Step4: Calculate D's value

Calculate \( 3\times4\times5 \). \( 3\times4 = 12 \), then \( 12\times5 = 60 \).

Answer:

A. \( 6\times6\times5 \)
