Practice makes perfect
To solve equations with a variable expression raised to a rational exponent, we raise each side of the equation to the greater reciprocal of the rational exponents.
xnm=k⇔(xnm)mn=kmn
Let's try to solve our equation using this method!
Finding the Solutions
We will first rearrange the equation such that the variable terms are on two different sides of the equation.
