What is the value of the expression below when z=7 ?

Question

what is the value of the expression below when 2=7?

Answer 1

Where's the expression?

Assuming you have a 'z' in the expression somewhere, simply replace the number '7' for each 'z' and solve the expression using the usually rules, like following the order of operations(i.e. you solve things in:parenthesis first).

Hope that's helpful!
