It's going to be 2 times 2, which is equal to 4. It's telling us that the slope over here is 4. That the slope, and I'm just using m. m is often the letter used to denote slope. They're saying that the slope of the tangent line there is 4, which seems completely, completely reasonable. So I encourage you to try this out yourself. I encourage you to try to estimate the slopes by calculating by taking points closer and closer around those points. And you'll see that the power rule really does give you results that actually make sense.
