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

Problem

(∫_^)(3/(x3)*d(x))

Solution

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

(∫_^)(3*x(−3)*d(x))

2. Apply the constant multiple rule by moving the constant factor outside the integral.

3*(∫_^)(x(−3)*d(x))

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

3⋅(x(−3+1))/(−3+1)+C

4. Simplify the exponent and the denominator.

3⋅(x(−2))/(−2)+C

5. Rewrite the expression by moving the negative exponent back to the denominator and simplifying the fraction.

−3/(2*x2)+C

Final Answer

(∫_^)(3/(x3)*d(x))=−3/(2*x2)+C
