    you can use cube root for \[x^3\] so that it would be x and then same goes for the right side, -8.

    no, you have to use the cube root, so \[\sqrt[3]{-8} \] is?

    you're looking for the value of your x, right?

    the value of your x is -2, remember when you have an equal sign what you do on the left side, should also be done on the right side :)
