Question 16277
A variable raised to a negative power, does NOT mean the answer is negative.  It means that the answer is a FRACTION in which the numerator is 1, and the denominator is the same variable raised to the positive power.  In other words, if you have {{{x^-7}}} it means that the numerator is 1, and the denominator is {{{x^7}}}.  So,


{{{x^-7 = 1/x^7}}}
