Final answer:

The product of the square roots √12, √18, and √30 is simplified to 36√5 by applying the properties of square roots and then factoring the resulting number to simplify the square root.

Step-by-step explanation:

The student is asking to find the product of three square roots: √12, √18, and √30. To simplify this expression, we can use the property of square roots that states √(a) × √(b) = √(a × b). Applying this property step by step we get:

√12 × √18 = √(12 × 18) = √(216),

Now we multiply this result by √30:

√(216) × √30 = √(216 × 30) = √(6480).

To further simplify, we need to factor 6480 into its prime factors and look for pairs of factors to eliminate the square root:

6480 = 2^4 × 3^4 × 5^1

Pull out the pairs from under the square root:

√6480 = √(2^4) × √(3^4) × √5 = 2^2 × 3^2 × √5 = 4 × 9 × √5 = 36√5

So the product of √12, √18, and √30 is 36√5.

Answer:


6√(6)

Step-by-step explanation:


√(12)√(18) =


= √(12 \cdot 18)


= √(4 \cdot 3 \cdot 9 \cdot 2)


= √(36 \cdot 6)


= √(36)√(6)


= 6√(6)
