Question

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

Answer 1

C

Explanation:

Answer 2

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
