Answer:

The integral of ∫x²√(5x-3)dx is (2/15) * (5x-3)^(3/2) + C, where C is the constant of integration.

Explanation:

To find the integral of ∫x²√(5x-3)dx, we can use a technique called u-substitution.

Let's begin by letting u = 5x-3. To find du, we can take the derivative of both sides with respect to x.

du/dx = 5

Next, we solve for dx by isolating it.

dx = du/5

Now, we can substitute these values back into the integral.

∫x²√(5x-3)dx = ∫x²√u(dx/5)

Simplifying further, we have:

(1/5) ∫x²√u du

To integrate this expression, we 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 not equal to -1.

Applying the power rule, we have:

(1/5) ∫x²√u du = (1/5) * (2/3) * (u^(3/2)) + C

Substituting u back in, we get:

(1/5) * (2/3) * (5x-3)^(3/2) + C

Therefore, the integral of ∫x²√(5x-3)dx is (2/15) * (5x-3)^(3/2) + C, where C is the constant of integration.
