Find the Derivative - d/dx 5x^4

Problem

(d(5)*x4)/d(x)

Solution

1. Identify the constant and the power of the variable x in the expression 5*x4

2. Apply the constant multiple rule, which states that (d(c)*ƒ(x))/d(x)=cd(ƒ(x))/d(x)

3. Apply the power rule, which states that d(xn)/d(x)=n*x(n−1)

4. Multiply the constant 5 by the exponent 4 and decrease the exponent by 1

5. Simplify the resulting expression.

Final Answer

(d(5)*x4)/d(x)=20*x3
