Which of the following is equivalent to (5)^7/3

kifflom [539]

<em>The answer is $\sqrt[3]{ 5^{7} }$ </em>

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>( $5^{7}$ is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index.

<em>Here's what a formula would look like:</em> $( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }$

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

in a square garden plot (with an area of 400 sq ft)deer fencing priced at $1.50 per foot is to be installed around the plot. if

mina [271]

We have a square garden of 400 square foot.

The area of a square is:

$A=x^2$

where x: side length.

In this case:

$\begin{gathered} A=400=x^2 \\ x=\sqrt[]{400}=20\text{ ft} \end{gathered}$

The perimeter of the square is the sum of the lengths of the sides of the square. As they are all equal, we can write:

$P=4x=4\cdot20=80\text{ ft}$

The fencing is priced at $1.50 per foot. If we add the 7% sales tax to this price we get:

$C=1.50\cdot(1+0.07)=1.50\cdot1.07=1.605\text{ \$/ft}$

The fencing will be installed in all the perimeter (80 ft).

We can calculate the total cost by multiplying the sales price ($1.605 per foot) and the perimeter (80 ft):

$F=C\cdot P=1.605\frac{\text{\$}}{\text{ft}}\cdot80\text{ ft}=\$128.40$

Answer: the fencing will cost a total of $128.40

Simplify x^3 y^3 / x^3 y^3

Marysya12 [62]

Answer:

$\frac{1}{y}$

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

$\frac{x*x*x*y*y*y}{x*x*x*y*y}$

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is $\frac{1}{y}$

Factor each trinomial. Then match the polynomial (term) on the left with its factored form (definition) on the right.
