Final answer:
We need the specific mathematical expressions to evaluate whether substituting n = 2 will yield a result greater than 30. A hypothetical example was provided for guidance but cannot definitively answer the question without the actual expressions.
Step-by-step explanation:
Without the list of expressions to evaluate when n = 2, it is impossible to determine which expression would be greater than 30. It's crucial to have specific mathematical expressions to work with, as the answer will vary depending on the operations and numbers involved within each expression.
To properly answer this question, replace the n variable with 2 in each given expression and calculate their values. The expressions that result in values greater than 30 are the ones that apply.
To better understand this process, let's use an hypothetical example: if one of the expressions given was n4 + 10, substituting 2 for n would give us 24 + 10 = 16 + 10 = 26, which is not greater than 30. Thus, this expression would not apply.
Remember, without the actual expressions, this explanation is hypothetical and intended to guide you on how to approach solving the problem once the expressions are provided.
