−4+x4=3

1 answer

To solve the equation \(-4 + x^4 = 3\), we can follow these steps:

  1. Add 4 to both sides of the equation:

    \[ x^4 = 3 + 4 \]

    \[ x^4 = 7 \]

  2. Now, take the fourth root of both sides:

    \[ x = \pm \sqrt[4]{7} \]

Thus, the solutions are:

\[ x = \sqrt[4]{7} \quad \text{and} \quad x = -\sqrt[4]{7} \]

You can also express \(\sqrt[4]{7}\) as \(7^{1/4}\), so the solutions can be written as:

\[ x = 7^{1/4} \quad \text{and} \quad x = -7^{1/4} \]
