Sure, I can help you with that!

To simplify the expression 5√18 × 2√8, you need to first simplify each square root individually and then perform the multiplication.

Step 1: Simplify the square roots: √18 can be simplified as follows: √18 = √(2 × 9) = √2 × √9 = √2 × 3 = 3√2

√8 can be simplified as follows: √8 = √(2 × 4) = √2 × √4 = √2 × 2 = 2√2

Step 2: Perform the multiplication: 5√18 × 2√8 = 5(3√2) × 2(2√2)

Now, multiply the coefficients (numbers outside the square roots) and simplify the square root term: 5(3√2) × 2(2√2) = 10√2 × √2

Step 3: Combine the square roots: Since both terms have the same square root (√2), you can combine them as follows: 10√2 × √2 = 10 × (√2 × √2)

Step 4: Simplify the square root of the product: √2 × √2 = √(2 × 2) = √4 = 2

Final Answer: The simplified expression is 10 × 2 = 20. So, 5√18 × 2√8 = 20.
