Below is a video tutorial on solving an equation with a negative rational exponent. Here are the steps.
1. Solve everything around the exponent. Get rid of any constants and coefficients.
2. Raise both sides of the equation to the reciprocal of the exponent.
3. Remember that the negative exponent flips the fraction.
4. Rewrite that as a radical and simplify it.
Don’t forget the ± when you take an even root.
