Are z^3 and 3z equivalent expressions? explain.​

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

let me know if you have questions

No

Step-by-step explanation:

z³ is equivalent to z×z×z while 3z is 3×z.

for example, if z = 2, z³ would become  2³, or 2×2×2 which equals 8.

But 3×2 is 6

so z³ and 3z arent equal
