Final answer:
The function f(z) provided is incoherent due to a typographical error, and thus, f(1) cannot be calculated accurately without proper clarification of the function's intended form.
Step-by-step explanation:
The provided function f(z)=z√² appears to contain a typographical error, as it is not mathematically coherent in its current form. Therefore, the exact computation of f(1) cannot be determined without further clarification on the correct form of the function. It is possible that the student intended to ask for the evaluation of a function with exponentiation or a specified operation that is not clear from the given expression.
