Math Problem Statement

4x3\int4x^3-2x+8x\sqrt{x}+8x+10

Solution

The integral provided appears to be:

(4x32x+8x+10)dx\int \left( 4x^3 - 2\sqrt{x} + 8x + 10 \right) \, dx

Let’s evaluate this integral term by term:

Step 1: Integrate 4x34x^3

4x3dx=4x44=x4\int 4x^3 \, dx = 4 \cdot \frac{x^4}{4} = x^4

Step 2: Integrate 2x-2\sqrt{x}

Rewrite x\sqrt{x} as x1/2x^{1/2}: 2x1/2dx=2x3/23/2=43x3/2\int -2x^{1/2} \, dx = -2 \cdot \frac{x^{3/2}}{3/2} = -\frac{4}{3}x^{3/2}

Step 3: Integrate 8x8x

8xdx=8x22=4x2\int 8x \, dx = 8 \cdot \frac{x^2}{2} = 4x^2

Step 4: Integrate 1010

10dx=10x\int 10 \, dx = 10x

Combine Results

Putting it all together, we get: (4x32x+8x+10)dx=x443x3/2+4x2+10x+C\int \left( 4x^3 - 2\sqrt{x} + 8x + 10 \right) \, dx = x^4 - \frac{4}{3}x^{3/2} + 4x^2 + 10x + C

where CC is the constant of integration.
