Well, this is going to be equal to, for x to the fifth, we can just use the power rule. We can bring the five out front and decrement the exponent by one, so it becomes five x, we could say to the five minus one power, which of course is just four. And then for this second one, we could do it in a few steps. Actually, let me just write it out here. So I could write, I could write the derivative with respect to x of two x to the third power is the same thing, it's equal to, the same, we could bring the constant out, the derivative with, two times the derivative with respect to x of x to the third power. This is one of our, this is one of our derivative properties. The derivative of a constant times some expression is the same thing as the constant times the derivative of that expression.
