x4=7

To solve the equation \( x^4 = 7 \), you can take the fourth root of both sides.

This gives:

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

So the solutions are:

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

If you want a numerical approximation, the fourth root of 7 is approximately:

\[ \sqrt[4]{7} \approx 1.626 \]

Thus, the two solutions are approximately:

\[ x \approx 1.626 \quad \text{and} \quad x \approx -1.626 \]
