Use the associative property of multiplication to write an expression equivalent to

8x*(4y*7z)

(8x*4y)*7z.

20

To use the associative property of multiplication, you can rearrange the grouping of the terms without changing the value of the expression.

Given the expression 8x * (4y * 7z), let's first simplify the inner parentheses by multiplying 4y and 7z:

8x * (4y * 7z)
= 8x * (28yz)

Now, we can apply the associative property by rearranging the grouping of the terms:

= (8x * 28yz)

To further simplify, we multiply the coefficients and combine the variables:

= 224xyz

Therefore, the expression equivalent to 8x * (4y * 7z) using the associative property of multiplication is 224xyz.
