how do I go about this the high power exponents has me lost t(x)=x^5 - 2x^3 + 4x^2 + 5 whats the gradient of tangent line when x=2

The derivative of is . If there is a constant, such as in the function , you just mulitply it by the exponent. So the derivative is just . So what is the derivative of ???
