You're probably finding this shockingly straightforward. So this is going to be 3 times x to the 3 minus 1 power. Or this is going to be equal to 3x squared. And we're done. In the next video, we'll think about whether this actually makes sense. Let's do one more example just to show it doesn't have to necessarily apply to only these kind of positive integers. We could have a scenario where maybe we have h of x. h of x is equal to x to the negative 100 power.
