Explain the difference between

(3z)^3 and 3z^3

Step-by-step explanation:

Brackets in mathematics are a little like periods in grammar.

They tell you exactly what you need to do.

In the question you have listed

3z^3 means that only the z is raised to the third power.

(3z)^3 means both the 3 and the z are raised to the third power. 3^3 * z^3 =

27 z^3     This is a valuable question to know the answer to.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
