Help, hurry up please
katrin2010 [14]

For this case we must find an expression equivalent to:

\frac {\sqrt [7] {x ^ 2}} {\sqrt [5] {y ^ 3}}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So, rewriting the expression we have:

\frac {x ^ {\frac {2} {7}}} {y ^ {\frac {3} {5}}} =

By definition of power properties we have:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

So:

x ^ {\frac {2} {7}} * y ^ {- \frac {3} {5}}

Answer:

Option A

Alecia builds a box in the shape of a cube with an open top. She plans to paint the box. Alecia calculates that there are 256 sq
STALIN [3.7K]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms

From the question, we understand that the cube has an open-top and the surface ares is 256 in^2

Let L represents the edge length, the surface area (S) is:

S = 5L^2

Substitute 256 for S

256 = 5L^2

Divide both sides by 5

51.2 = L^2

Take square roots of both sides:

\sqrt{51.2} = L

7.155= L

L=7.16in ---- approximated

The volume of the cube is:

Volume = L^3

Volume = \sqrt{51.2}^3

Volume = 366.3573

Volume = 366.36in^3

<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>
