Evaluate the Integral integral of 3/(x^2) with respect to x

Problem

(∫_^)(3/(x2)*d(x))

Solution

1. Rewrite the integrand using a negative exponent to make it easier to apply the power rule for integration.

(∫_^)(3*x(−2)*d(x))

2. Apply the power rule for integration, which states that (∫_^)(xn*d(x))=(x(n+1))/(n+1) for n≠−1

3⋅(x(−2+1))/(−2+1)+C

3. Simplify the exponent and the denominator.

3⋅(x(−1))/(−1)+C

4. Simplify the expression by multiplying the constants and rewriting the negative exponent as a fraction.

−3*x(−1)+C

−3/x+C

Final Answer

(∫_^)(3/(x2)*d(x))=−3/x+C
