Find the error may happened

You are testing the exp function above. Which of the following test cases would detect errors which exist in the function (hint: there is an bug)

I check the documents, but there are no information about exp(number,number)

Does anyone may tell me what is the meaning of exp(0,2) or where can find the information about that.

Thank you.

The inbuilt exp function takes only one input. But what you have shown it takes two inputs, it might be your defined function.

OK, thank you.

I suspect that the part "above" defines a function exp(a,b) that is responsible for calculating a to the power b
