Answer 7

2x square root(14)

Answer 8

We can simplify by rationalizing the denominator in the following way:

(4 square root(6))/(square root(30)) * (square root(30))/(square root(30))

= (4 square root(6) square root(30))/(30)

= (4 square root(180))/(30)

= (4 square root(36*5))/(30)

= (4 * 6 square root(5))/(30)

= (24 square root(5))/(30)

= (12 square root(5))/(15)

= 4/5 * square root(5)

Therefore, (4 square root(6))/(square root(30)) = 4/5 * square root(5).

Answer 9

To simplify, we need to break down 150, x^3 and k^4 into their prime factors:

150 = 2 * 3 * 5^2
x^3 = x^2 * x
k^4 = (k^2)^2

Now we can simplify the original expression as follows:

square root(150 x^3 k^4)
= square root(2 * 3 * 5^2 * x^2 * x * k^2 * k^2)
= square root(2 * 3 * 5^2) * square root(x^2) * square root(x) * square root(k^2) * square root(k^2)
= 5xk^2 * square root(6x)

Therefore, the simplified radical expression is 5xk^2 * square root(6x).

Answer 10

We can simplify this expression as follows:

square root(14q) * 2 square root(4q)
= square root(2 * 7 * q) * 2 * square root(2 * 2 * q)
= (square root(2) * square root(7) * square root(q)) * 2 * (2 * square root(q))
= (2 * square root(2) * square root(7) * square root(q)) * (2 * square root(q))
= 4 * 2 * square root(2 * 7) * square root(q) * square root(q)
= 8q * square root(14)

Therefore, the simplified radical expression is 8q * square root(14).

Answer 11

No problem. Here's how to get to the correct answer:

square root(14q) * 2 square root(4q)

= square root(14q) * 2 * 2 square root(q) (since 4q = 2*2*q)

= 2 * square root(14q) * 2 square root(q)

= 4 square root(14q^2)

= 4q square root(14)

Therefore, the simplified radical expression is 4q square root(14), which matches with the second answer choice.

Answer 12

We can simplify this expression by breaking down the numerator into its prime factors:

sqrt(20x^13 y^5) = sqrt(2*2*5*x^12*x*y^4*y)

Then, we can simplify the expression as follows:

sqrt(20x^13 y^5) / (5xy^7)

= (sqrt(2*2*5*x^12*x*y^4*y)) / (5xy^7)

= (2x^6 y^2 * sqrt(5x)) / (5xy^7)

= (2x^5 * sqrt(5x)) / (5y^5)

Therefore, the simplified radical expression is (2x^5 * sqrt(5x)) / (5y^5).

Answer 13

No problem. Let's see how we can simplify the expression to match one of the answer choices.

sqrt(20x^13 y^5) / (5xy^7)

= sqrt(4 * 5 * x^12 * x * y^4 * y) / (5xy^7)

= (2x^6y^2 * sqrt(5x)) / (5xy^7)

= (2x^6 * sqrt(5x)) / (5y^5)

This simplifies to the third answer choice: 2 sqrt(x^12) / y^2.

So, the simplified radical expression is 2 sqrt(x^12) / y^2.
