Answer:
I think the answer should be 20
Answer:
5
Step-by-step explanation:
To write it in standard form, we set the equation equal to 0. To do this, we add 6 to each side:
-6+6 = x² + 4x - 1 + 6
0 = x² + 4x + 5
The related function is
y = x² + 4x + 5
The value of c in this function is 5.

Step-by-step explanation:
<h3>210° × π/180 = 3.665rad</h3>
It would help to have the question. But I'll guess
![\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}} = ((x^{\frac 3 5})^{\frac 1 4}) }{ x} = x^{\frac 3{20}} x = x \sqrt[20]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E%7B%5Cfrac%203%205%7D%7D%7B%5Csqrt%7Bx%5E2%7D%7D%20%3D%20%28%28x%5E%7B%5Cfrac%203%205%7D%29%5E%7B%5Cfrac%201%204%7D%29%20%7D%7B%20x%7D%20%3D%20x%5E%7B%5Cfrac%203%7B20%7D%7D%20x%20%20%3D%20x%20%5Csqrt%5B20%5D%7Bx%5E3%7D)
2nd choice.
I forgot the explanation because I was so glad to have puzzled out the question.
The fourth root is the same as the 1/4 th power.
If we know x is positive

![\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E%7B%5Cfrac%203%205%7D%7D%7B%5Csqrt%7Bx%5E2%7D%7D)

We multiply the powers:


The one-twentieth power is the twentieth root. We bring the additional factor of x to the front.
