Which Expression is Equivalent to ${$ (xy)z$}$?

Understanding the Problem

When dealing with algebraic expressions, it's essential to understand the order of operations and how to manipulate them to simplify or find equivalent expressions. In this case, we're given the expression ${$ (xy)z$}$ and asked to determine which of the provided options is equivalent to it.

The Distributive Property

To approach this problem, we need to recall the distributive property of multiplication over addition. This property states that for any numbers a, b, and c, the following equation holds:

a(b + c) = ab + ac

We can use this property to expand the given expression ${$ (xy)z$}$ and see if it matches any of the options.

Expanding the Expression

Using the distributive property, we can expand the expression ${$ (xy)z$}$ as follows:

${$ (xy)z$}$ = ${$ x(yz)$}$

This is because we can distribute the z to both the x and the y, resulting in x multiplied by the product of y and z.

Comparing with Options

Now that we have expanded the expression, let's compare it with the options provided:

A. ${$ (x+y)+z$}$ - This option is not equivalent to the expanded expression, as it involves adding x and y before multiplying by z.

B. ${ $2z(xy)\$}$ - This option is not equivalent to the expanded expression, as it involves multiplying z by the product of x and y, but also includes a factor of 2.

C. ${$ x(yz)$}$ - This option is equivalent to the expanded expression, as it matches the result of distributing z to both the x and the y.

D. ${$ x(y+z)$}$ - This option is not equivalent to the expanded expression, as it involves adding y and z before multiplying by x.

Conclusion

Based on the distributive property and the expansion of the given expression, we can conclude that the correct answer is:

C. ${$ x(yz)$}$

This option is equivalent to the expanded expression, and it correctly represents the result of distributing z to both the x and the y.
