Option C is correct

Step-by-step explanation:

We need to simplify the radical

$\sqrt{\frac{20x^{13}y^5}{5xy^7}}$

We know that a^m/a^n = a^m-n and 20/5 = 4

Solving

$\sqrt{4x^{13-1}y^{5-7}}\\\sqrt{4x^{12}y^{-2}}\\$

Now, √4 = 2 and a^-m = 1/a^m

Applying,

$2\sqrt{\frac{x^{12}}{y^2}}\\$

So, Option C $2\sqrt{\frac{x^{12}}{y^2}}\\$ is correct.

Step-by-step explanation:

The formula is y-b=m(x-a)

m is the slope

a is the x term

b is the y term

y-6=3(x-5)
