Find the Derivative - d/d@VAR f(x)=2/(x^2)

Problem

d()/d(x)2/(x2)

Solution

1. Rewrite the expression using a negative exponent to make it easier to differentiate.

2/(x2)=2*x(−2)

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

(d(2)*x(−2))/d(x)=2⋅(−2)*x(−2−1)

3. Simplify the coefficients and the exponent.

2⋅(−2)*x(−3)=−4*x(−3)

4. Rewrite the result with a positive exponent by moving the variable back to the denominator.

−4*x(−3)=−4/(x3)

Final Answer

d()/d(x)2/(x2)=−4/(x3)
