To integrate (\int (4x+5)^3 dx) using substitution, let (u = 4x + 5). Then, (du/dx = 4) or (dx = du/4). Substitute these into the integral to get (\int u^3 \cdot (1/4) du). Now, integrate (\int u^3 \cdot (1/4) du) to get ((1/4) \cdot (u^4/4) + C), where (C) is the constant of integration. Finally, substitute back (u = 4x + 5) to get the final answer of ((1/64)(4x+5)^4 + 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.
