To evaluate the integral ∫(13x^2 + 12x^(-2))dx, you can use the power rule for integration. The power rule states that the integral of x^n with respect to x is (x^(n+1))/(n+1), where n is any real number except -1. Applying this rule to each term separately, we get:

∫(13x^2 + 12x^(-2))dx = (13/3)x^(2+1) + 12(-2+1)x^(-2+1) + C

Simplifying further:

∫(13x^2 + 12x^(-2))dx = (13/3)x^3 - 24x^(-1) + C

Therefore, the integral of (13x^2 + 12x^(-2))dx is equal to (13/3)x^3 - 24x^(-1) + C, where C is the constant of integration.

To evaluate the integral ∫(13x^2 + 12x^(-2)) dx, you need to apply the power rule for integration. For each term, add 1 to the exponent and divide the coefficient by the new exponent. So, integrate each term separately:

∫13x^2 dx = (13/3) * x^3 + C ∫12x^(-2) dx = 12 * (x^(-1))/(-1) + C

Combine the results to get the final integral:

∫(13x^2 + 12x^(-2)) dx = (13/3) * x^3 - 12/x + C

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
