This problem could be two different things:

You could of meant: Evalute 3z when z=9

If thats what you wanted here:

Answer: 27

Explanation: Substitute: 3x9 Calculate the product or quotient: 27

Or what this says, evaluate 3z3z3, z when z=9z=9z, equals, 9

The answer is 108. Because you multiply 3 by 9. which is 27 then you multiply 27 by 4 because thats how many 3zs there are.
