To divide √410 by √2, we can rationalize the denominator.
We multiply both the numerator and denominator by √2 to rationalize the denominator:
(√410 * √2) / (√2 * √2)
= (√(410 * 2)) / (2)
= (√820) / 2
Therefore, the exact answer is (√820) / 2.

Divide 4√10/√2
To divide 4√10 by √2, we need to rationalize the denominator.
First, let's simplify the numerator: 4√10.
Next, let's rationalize the denominator: √2.
To rationalize the denominator, we multiply both the numerator and denominator by the conjugate of √2, which is also √2. Multiplying the expression by √2/√2, we get:
(4√10 * √2) / (√2 * √2)
= (4√(10 * 2)) / (√(2 * 2))
= (4√20) / √4
= (4√20) / 2
= 2√20
= 2 * √(4 * 5)
= 2 * √(20)
= 2 * √(4 * 5)
= 2 * 2√5
= 4√5
Therefore, the exact answer is 4√5.

= 2 * √(4 * 5)
= 2 * √(20)
= 2 * √(4 * 5)
= 2 * 2√5
= 4√5
Therefore, the exact answer is 4√5.
Simplify 300−−−√ .(1 point)
To simplify √300, we can factorize 300 and find perfect square factors:
300 = 2 * 2 * 3 * 5 * 5 = 2^2 * 3 * 5^2
Taking the square root of the perfect square factors:
√300 = √(2^2 * 3 * 5^2) = 2 * √(3 * 5^2) = 2 * 5 √3 = 10√3
So, √300 simplifies to 10√3.
300 = 2 * 2 * 3 * 5 * 5 = 2^2 * 3 * 5^2
Taking the square root of the perfect square factors:
√300 = √(2^2 * 3 * 5^2) = 2 * √(3 * 5^2) = 2 * 5 √3 = 10√3
So, √300 simplifies to 10√3.
Simplify 1327−−√ .
Unfortunately, √1327 cannot be simplified further, as it is not a perfect square. Therefore, the simplification of √1327 is simply √1327.
Simplify 13√27
To simplify 13√27, we can factorize 27 and find perfect square factors:
27 = 3 * 3 * 3 = 3^3
Taking the square root of the perfect square factor:
√27 = √(3^3) = 3√3
Therefore, 13√27 simplifies to 13 * 3√3, which can be further simplified to 39√3.
27 = 3 * 3 * 3 = 3^3
Taking the square root of the perfect square factor:
√27 = √(3^3) = 3√3
Therefore, 13√27 simplifies to 13 * 3√3, which can be further simplified to 39√3.
