The correct Answer is:
To solve the question "By how much does `sqrt(12) + sqrt(18)` exceed `sqrt(3) + sqrt(2)`?", we will follow these steps: ### Step 1: Simplify `sqrt(12)` and `sqrt(18)` We can simplify the square roots: - `sqrt(12) = sqrt(4 * 3) = sqrt(4) * sqrt(3) = 2 * sqrt(3)` - `sqrt(18) = sqrt(9 * 2) = sqrt(9) * sqrt(2) = 3 * sqrt(2)` ### Step 2: Combine the simplified square roots Now we can combine the simplified forms: - `sqrt(12) + sqrt(18) = 2 * sqrt(3) + 3 * sqrt(2)` ### Step 3: Simplify `sqrt(3) + sqrt(2)` The expression `sqrt(3) + sqrt(2)` remains as it is since it cannot be simplified further. ### Step 4: Find the difference Now we need to find how much `sqrt(12) + sqrt(18)` exceeds `sqrt(3) + sqrt(2)`: - Difference = `(2 * sqrt(3) + 3 * sqrt(2)) - (sqrt(3) + sqrt(2))` ### Step 5: Combine like terms Now, we combine the like terms: - Difference = `(2 * sqrt(3) - sqrt(3)) + (3 * sqrt(2) - sqrt(2))` - Difference = `1 * sqrt(3) + 2 * sqrt(2)` ### Final Answer Thus, `sqrt(12) + sqrt(18)` exceeds `sqrt(3) + sqrt(2)` by `sqrt(3) + 2 * sqrt(2)`.
