Simplifying Cube Roots

In Magic the Gathering, any card you have requires a certain amount of "mana" points to be paid in order for you to play the card. A mathematician made a card that requires you to solve for $x$ to determine how much "mana" you need to pay. The equation is as follows: $$\sqrt[3]{4096x^6} = 144$$

Solve for $x$. How much mana will need to be paid in order to play the card?
