Final answer:
The statement is False: let expressions and function application are not syntactically equivalent.
Step-by-step explanation:
The statement True or False: let expression and function application are syntactically equivalent is False.
In computer science, a let expression allows you to define a variable and assign a value to it within a specific scope. It is commonly used in functional programming languages like Haskell and ML. On the other hand, function application is the process of invoking a function with specific arguments.
Although both involve evaluating expressions, they are not syntactically equivalent. Let expressions define variables and assign values, while function application calls a function with arguments and returns a result.
