Based on the mathematical expression shown below, create a function that calculates the value of the variable y. The variable x and the variable z must be parameters ("parameters" or "arguments") of the function. The function hasto return ("return") the value of the variable y. Import any module you deem necessary to complete the problem. (Hint: The math module has functions (for example, log, factorial) and values (for example, pi) that you can use.)

y = x! log (7) 1 -XZ
