Q. For the following equation, find f′(x).f(x)=7x5+5Answer: f′(x)=
Identify Function: Identify the function to differentiate.We are given the function f(x)=7x5+5, and we need to find its derivative, which is denoted by f′(x).
Apply Power Rule: Apply the power rule for differentiation. The power rule states that the derivative of xn with respect to x is n∗x(n−1). We will apply this rule to the term 7x5.
Differentiate 7x5: Differentiate the term 7x5. Using the power rule, the derivative of 7x5 is 5×7x(5−1)=35x4.
Differentiate Constant: Differentiate the constant term 5. The derivative of a constant is 0, so the derivative of 5 with respect to x is 0.
Combine Derivatives: Combine the derivatives of all terms to find f′(x).f′(x)=35x4+0 Simplify the expression by removing the 0.$f′(x)=35x4)
