To solve the equation
, we can start by isolating one of the square roots. Let's isolate
:
Now, square both sides to eliminate the square root:\( \sqrt[4]{x}+7 = (\sqrt{x}-7)^2 \)
Next, let's isolate
:
Now, raise both sides to the power of 4 to eliminate the fourth root:\( x = (x-14\sqrt{x}+42)^4 \)This equation is quite complex to solve directly. However, we can try to find a solution by substituting some values for
and checking if they satisfy the equation.Let's try
:
So,
is not a solution.Let's try
:
So,
