I guess since you have the correct answer there that you need to know how to get it. Start by rewriting that exponent as a radical. It would look like this: . The first step is to undo that square root by squaring both sides. That will give you this:
. Next we have to undo that cubing by taking the cubed root of both sides, leaving us with this:
. We add 8 to both sides to get 8x = 24 and x = 3.
