WebFractional exponents are equivalent to roots as shown in the following exponential rule: x a b = x a b. Using this expression, you can write any fractional exponent as a root. x 1 2 = x. x 1 3 = x 3. x 2 3 = x 2 3. You can use the same expression to write any root as a fractional exponent. x 4 = x 1 4. x 5 6 = x 5 6. WebI was just wondering how someone would compute say: $$(-5)^{2/3}$$ I have tried a couple ways to simplify this and I am not sure if the number stays negative or turns into a positive. I know that if a negative number is raised to an odd power it is negative, but fractional powers are neither odd or even.
