Find the Derivative - d/dx 4/x

Problem

d()/d(x)4/x

Solution

1. Rewrite the expression using a negative exponent to make it easier to apply the power rule.

4/x=4*x(−1)

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

(d(4)*x(−1))/d(x)=4⋅(−1)*x(−1−1)

3. Simplify the exponent and the coefficient.

4⋅(−1)*x(−2)=−4*x(−2)

4. Convert the expression back into fraction form by moving the variable with the negative exponent to the denominator.

−4*x(−2)=−4/(x2)

Final Answer

d()/d(x)4/x=−4/(x2)
