Exercise for reference:

Please try to guess what is missing in the following code and add the missing part so that the code works fine.

Answer:

import math
print(math.pow(2, 3))

Explanation:

You could pass any number there, so 3 is just an example.As the error suggested, you simply needed to pass a second argument so that pow can calculate the power of the first argument.

If you didn't understand the error, you could do help(math.pow) to see how the method works.
