Please fix the test suite so rounding isn't required to get the correct answer for x=25.
I agree with James: for test 3 the true answer is 623360743125120. It should also be clarified in the problem statement that the function input "x" corresponds to n² (not n). Lastly, it is better not to format the problem statement as if it were code.
I agree with everyone. My guess is that the author was using the short format for numbers and just copied 6.2336e+14. If you write format long and do the calculation again, you may see the correct answer.
