Note:
Many math textbooks will show answers as follows: your answer should always be in the form with which you started.
Example 1: if your problem begins with a mixed number, then your answer should be in a mixed number instead of a fraction.
Example 2: if your problem begins with a fractional exponent, then your answer should be with exponents instead of in radical form.
Example 3: if your problem begins with an radical, then your answer should be with a radical instead of in exponent form.
The exception to these three examples are when the problem reduces to a whole number.
