To solve the equation \( 5x^4 - 3^2 - 5 = 0 \), we can first simplify the equation.
First, calculate \( 3^2 \):
\[ 3^2 = 9 \]
Now, substitute that back into the equation:
\[ 5x^4 - 9 - 5 = 0 \]
Combine like terms:
\[ 5x^4 - 14 = 0 \]
Now, add 14 to both sides of the equation:
\[ 5x^4 = 14 \]
Next, divide both sides by 5:
\[ x^4 = \frac{14}{5} \]
Now, take the fourth root of both sides:
\[ x = \pm \sqrt[4]{\frac{14}{5}} \]
This can also be simplified as:
\[ x = \pm \frac{\sqrt[4]{14}}{\sqrt[4]{5}} \]
So, the solutions to the equation \( 5x^4 - 3^2 - 5 = 0 \) are:
\[ x = \frac{\sqrt[4]{14}}{\sqrt[4]{5}} \quad \text{and} \quad x = -\frac{\sqrt[4]{14}}{\sqrt[4]{5}} \]
