Understanding the Problem

The given problem involves simplifying a product of square roots. We are asked to assume that $x \geq 0$ and simplify the expression $2 \sqrt{8 x^3}\left(3 \sqrt{10 x^4} - x \sqrt{5 x^2}\right)$. This problem requires us to apply the properties of square roots and simplify the expression step by step.

Step 1: Simplify the Square Roots

To simplify the square roots, we can start by expressing each square root in terms of its prime factors. We have:

$$\sqrt{8 x^3} = \sqrt{2^3 x^3} = 2 x \sqrt{x}$$

$$\sqrt{10 x^4} = \sqrt{2 \cdot 5 x^4} = x^2 \sqrt{10 x}$$

$$\sqrt{5 x^2} = \sqrt{5 x^2}$$

Now, we can substitute these simplified expressions back into the original product.

Step 2: Substitute the Simplified Expressions

Substituting the simplified expressions, we get:

$$2 \sqrt{8 x^3}\left(3 \sqrt{10 x^4} - x \sqrt{5 x^2}\right) = 2 (2 x \sqrt{x}) \left(3 (x^2 \sqrt{10 x}) - x (\sqrt{5 x^2})\right)$$

Step 3: Simplify the Product

Now, we can simplify the product by multiplying the terms together:

$$2 (2 x \sqrt{x}) \left(3 (x^2 \sqrt{10 x}) - x (\sqrt{5 x^2})\right) = 4 x \sqrt{x} \left(3 x^2 \sqrt{10 x} - x \sqrt{5 x^2}\right)$$

Step 4: Distribute the Terms

To simplify the expression further, we can distribute the terms:

$$4 x \sqrt{x} \left(3 x^2 \sqrt{10 x} - x \sqrt{5 x^2}\right) = 4 x \sqrt{x} (3 x^2 \sqrt{10 x}) - 4 x \sqrt{x} (x \sqrt{5 x^2})$$

Step 5: Simplify the Terms

Now, we can simplify the terms by combining like terms:

$$4 x \sqrt{x} (3 x^2 \sqrt{10 x}) - 4 x \sqrt{x} (x \sqrt{5 x^2}) = 12 x^3 \sqrt{10 x^3} - 4 x^2 \sqrt{5 x^3}$$

Step 6: Simplify the Square Roots

To simplify the square roots, we can express each square root in terms of its prime factors:

$$12 x^3 \sqrt{10 x^3} - 4 x^2 \sqrt{5 x^3} = 12 x^3 \sqrt{2 \cdot 5 x^3} - 4 x^2 \sqrt{5 x^3}$$

Step 7: Factor Out the Common Terms

Now, we can factor out the common terms:

$$12 x^3 \sqrt{2 \cdot 5 x^3} - 4 x^2 \sqrt{5 x^3} = 4 x^2 (3 x \sqrt{10 x} - \sqrt{5 x})$$

Step 8: Simplify the Expression

Finally, we can simplify the expression by combining like terms:

$$4 x^2 (3 x \sqrt{10 x} - \sqrt{5 x}) = 12 x^3 \sqrt{10 x} - 4 x^2 \sqrt{5 x}$$

Conclusion

The simplified product is $12 x^3 \sqrt{10 x} - 4 x^2 \sqrt{5 x}$. This is the final answer to the problem.
