And in future videos, we'll get a sense of why it makes sense and even prove it. So the power rule just tells us that if I have some function, f of x, and it's equal to some power of x, so x to the n power, where n does not equal 0. So n can be anything. It can be positive and negative. It does not have to be an integer. The power rule tells us that the derivative of this, f prime of x, is just going to be equal to n. So you're literally bringing this out front. n times x.
