Find the Derivative - d/dx x^7e^x

Problem

d()/d(x)*x^7*e^x

Solution

1. Identify the rule needed for the derivative of a product of two functions, u(x)=x^7 and v(x)=e^x

2. Apply the product rule formula, which states (d(u)*v)/d(x)=ud(v)/d(x)+vd(u)/d(x)

3. Differentiate the individual components: d(x^7)/d(x)=7*x^6 using the power rule and d(e^x)/d(x)=e^x

4. Substitute these derivatives back into the product rule formula.

(d(x^7)*e^x)/d(x)=x^7d(e^x)/d(x)+e^xd(x^7)/d(x)

5. Simplify the expression by performing the multiplication.

(d(x^7)*e^x)/d(x)=x^7*e^x+7*x^6*e^x

6. Factor out the greatest common factor, which is x^6*e^x

(d(x^7)*e^x)/d(x)=x^6*e^x*(x+7)

Final Answer

(d(x^7)*e^x)/d(x)=x^6*e^x*(x+7)
