Which expression is equivalent to square root 8/x^6? assume x > 0
Alik [6]
<h2>Answer:</h2>

<u>The equivalent expression is </u><u> (2 / x ^ 3) * sqrt (2)</u>

<h2>Step-by-step explanation:</h2>

We have sqrt 8 / x ^ 6

 Rewriting the expression:

 =sqrt (8 / x ^ 6)

 =sqrt (2 * 4 / ((x ^ 2) * (x ^ 2) * (x ^ 2)))

 =(2 / (x * x * x)) sqrt (2)

= (2 / x ^ 3) * sqrt (2)

We get finally

 (2 / x ^ 3) * sqrt (2)

You have a fishing line spool with an end that has an area of 20.0 cm2. How much fishing line do you need to wind around the spo
lana66690 [7]
<h3>Problem Solution</h3>

Assuming the spool is a cylinder and the circumference we're winding around is that of a circle with the given area, we can write the relation between circumference and area as

... C = 2√(πA)

10 times the circumference is then

... 10C = 20√(π·20 cm²) = 40√(5π) cm ≈ 159 cm

<h3>Formula Derivation</h3>

The usual formulas for circumference and area are

... C = 2πr

... A = πr²

If we multiply the area formula by π and take the square root, we get

... πA = (πr)²

... √(πA) = πr

Multiplying this by 2 gives circumference.

... C = 2√(πA) = 2πr
