Answer:

no, they are not.

Step-by-step explanation:

3z means a number multiplied by 3

so if z is 2, 3(2) = 6

but z^3 means z multiplied by z, and then multiplied by z again.

so if z is 2, it's 2x 2 = 4 x 2 = 8

The two expressions are not equivalent to each other.

What are equivalent expressions?

Equivalent expressions are expressions that are equal and synonyms to each other when used differently with various mathematical concepts.

From the expressions given:

  • z^3
  • 3z

  • The first expression is a variable (z) raised to a power of 3. The power is also called an exponent.
  • The second expression is a variable(z) that has a coefficient of 3

Let us assume that:

z^3 = 3z

Now, let's replace 2 for the value of z on both sides, we have:

(2)^3 = 3(2)

8 ≠ 6
