Answer:

\frac{2\sqrt{2}}{x^3}

Step-by-step explanation:

\sqrt{\frac{8}{x^6} }

To simplify the given expression we take square root for the top and bottom

\frac{\sqrt{8} }{\sqrt{x^6} }

\sqrt{8} =\sqrt{4*2} =2\sqrt{2}

\sqrt{x^6} =\sqrt{x^3*x^3} =x^3

Replace it in our problem

\frac{2\sqrt{2}}{x^3}

<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)

2. A student on the track team runs 45 minutes each day as a part of her training. She
fomenos

Answer:

D

Step-by-step explanation:

The basic equation to solve this would be D = RT, which is

D is Distance

R is Rate (speed)

T is time

To find total distance D, we can find individual distances for two legs of the whole.

First Leg:

R = 8

T = a

D = 8a

Second Leg:

R = 7.5

T = b

D = 7.5b

Total distance D is:

D = 8a + 7.5b

Moreover, we know student runs 45 minutes in total hence a + b = 45 or we can say a = 45 - b, so we can replace this in the equation found:

D = 8a + 7.5b

D = 8(45 - b) + 7.5b

Answer choice D is right.
