Final answer:

To evaluate the integral, a substitution can simplify the expression, and after integration, the constant of integration 'C' is added.

Step-by-step explanation:

Evaluating an Integral

The student has asked to evaluate the following integral:

∫ x⁴ √(x² - 3) dx,

where 'C' is used for the constant of integration. To properly evaluate this integral, one would typically look for a substitution that simplifies the integral or leverage integration by parts if necessary. In this case, a substitution of 'u' for 'x² - 3' could be a starting point, as it simplifies the integral to:

∫ (u + 3)² √(u) (1/2)du,

after adjusting for 'dx'. Following the integration, we add the constant 'C' to represent the constant of integration. This method is aligned with the principle of reducing an integral to a more manageable form, as discussed in example 7.4
