Question

2. True or False? Show how you know64 x 8 x 100 = 640 x 8 x 10

Answer 1

True

Step-by-step explanation

We want to know if the expression on the right is equal to the one on the left.

We can do this by expanding 100 on the left hand side so it becomes 10 * 10, so we have:

64 * 8 * 10 * 10

We can redistribute one of the 10s to the front of the expression:

64 * 10 * 8 * 10

=> 640 * 8 * 10

This is identical to the expression on the right. Therefore, it is True that:

64 * 8 * 100 = 640 * 8 * 10
