We are given the following equation:

To solve this equation we will take the square root to both sides:
![x=\sqrt[]{-54}](https://img.qammunity.org/2023/formulas/mathematics/college/p2c3ikkqzie7ek239oxt5icf9zpfbx3pmu.png)
We are given that "x" is a real number, but the square root of a negative number does not exist in the real numbers therefore, this equation has no solution.
