Multiply (square root7)x(−square root2) . Give an exact answer.
To multiply square roots, you can multiply the numbers under the square roots together and keep the square root of the product.
The product of (square root of 7) and (-square root of 2) is:
√7 * (- √2)
√(7 * 2) * (-1) (Multiplying the numbers under the square roots together)
√14 * (-1)
The exact answer is -√14.

To divide by a number outside of the square root, you can divide each term inside the square root individually by that number.
Given the expression 8√6 / 2, we can divide both the coefficient (8) and the term inside the square root (√6) individually by 2.
8 / 2 = 4
√6 / 2 = √(6/2) = √3
So, the exact answer is 4√3.

To divide square roots, you can divide the numbers inside the square roots while keeping the square root symbol.
Given the expression (4√10) / √2, we can divide the numbers inside the square roots:
√10 / √2 = √(10/2) = √5
So, the exact answer is 4√5.

We can simplify the square root of 300 by factoring it into perfect squares.
First, we factor 300:
300 = 100 * 3
Then, we can simplify the square root by taking the square root of each perfect square factor:
√300 = √(100 * 3) = √100 * √3 = 10√3
So, the simplified form is 10√3.

To simplify the expression 13√27, we can factor the number 27 into perfect squares.
27 can be factored as 3 * 3 * 3, which means it has a perfect square factor of 3.
We can simplify the expression by taking out the perfect square factor outside the square root:
13√27 = 13√(3 * 3 * 3) = 13 * 3√3 = 39√3
Therefore, the simplified form of 13√27 is 39√3.
