Numbers to the power of negative fractions
Web2 sep. 2016 · In algebra we may want to consider the function 1 / ( x 2 − 1), or 1 / ( x 2 − a 2) for all x, and sometimes the denominator is negative. Or in trigonometry consider tan x = ( sin x) / ( cos x). For many x -intervals the denominator is negative. How awkward to try to avoid that! – KCd Sep 4, 2016 at 16:39 Add a comment 2 Web25 apr. 2024 · In fact, the rule of "numerator as power, denominator as root" applies to all exponents -- even whole-number exponents and fractional exponents with a numerator of 1. For example, the whole number 2 is the equivalent of the fraction 2/1. So the exponential expression 9^2 is "really" 9^2/1. Raising 9 to the 2nd power gives you 81.
