Question

Which of the following occurs within the solution process for 3√5x-2-3√4x=0

Answer 1

For this case we have the following expression:

$\sqrt [3] {5x-2} - \sqrt [3] {4x} = 0$

If we add to both sides of the equation $\sqrt [3] {4x}$ we have:

$\sqrt [3] {5x-2} = \sqrt [3] {4x}$

To eliminate the roots we must raise both sides to the cube:

$(\sqrt [3] {5x-2}) ^ 3 = (\sqrt [3] {4x}) ^ 3\\5x-2 = 4x$

So, the correct option is the option c

Answer:

Option C
