Multiply by .
Since the expression on each side of the equation has the same denominator, the numerators must be equal.
Take the 4th root of both sides of the equation to eliminate the exponent on the left side.
The complete solution is the result of both the positive and negative portions of the solution.
Tap for more steps…
First, use the positive value of the to find the first solution.
Next, use the negative value of the to find the second solution.
The complete solution is the result of both the positive and negative portions of the solution.
To rewrite as a function of , write the equation so that is by itself on one side of the equal sign and an expression involving only is on the other side.
