This is going to be 2 times derivative of x to the fifth. Well, the power rule tells us n is 5. It's going to be 5x to the 5 minus 1, or 5x to the fourth power. So it's going to be 5x to the fourth power, which is going to be equal to 2 times 5 is 10x to the fourth. So 2x to the fifth, you can literally just say, OK, the power rule tells me the derivative of that is 5x to the fourth. 5 times 2 is 10. So that simplifies our life a good bit.
