In order to convert from radical to exponential form, we can use the property below:

\sqrt[c]{a^b}=a^{\frac{b}{c}}

Then, to find the simplest form, we use this property:

\begin{gathered} a^b\cdot a^c=a^{b+c} \\ a^b\colon a^c=a^{b-c} \end{gathered}

So we have:

\begin{gathered} \sqrt[5]{x^3}=x^{\frac{3}{5}} \\ \sqrt[]{x^4}=x^{\frac{4}{2}} \\ \sqrt[]{x^3}=x^{\frac{3}{2}} \\  \\ \sqrt[5]{x^3}\cdot\sqrt[]{x^4}\colon\sqrt[]{x^3} \\ =x^{\frac{3}{5}}\cdot x^{\frac{4}{2}}\colon x^{\frac{3}{2}} \\ =x^{\frac{3}{5}+\frac{4}{2}-\frac{3}{2}} \\ =x^{\frac{3}{5}+\frac{1}{2}} \\ =x^{\frac{6}{10}+\frac{5}{10}} \\ =x^{\frac{11}{10}} \\ =x^1\cdot x^{\frac{1}{10}} \\ =x\sqrt[10]{x} \end{gathered}

Function help please

Answer:

The first table represents a function.

Step-by-step explanation:

For it to be a function, there needs to be 1 unique y value of 1 unique x value.

  • Looking at 2nd table, we see x value of -5 is mapped to 2 different y values of -5 and 5. So this is not a function.
  • Looking at 3rd table, we see x value of -2 is mapped to 2 different y values of 2 and 4. So this is not a function.
  • Looking at 4th table, we see x value of -4 is mapped to 2 different y values of 2 and 0. So this is not a function as well.

Looking at table 1, there are no duplicate x values and each of the 4 x values map to different values. So the first table represents a function.

How you can tell whether a line’s slope is greater than 1, equal to 1, or less than 1.
bixtya [17]

Answer:

You first find two points on the graph. You then count the distance between the two y-values (vertical) then the distance between the two x values (horizontal). The slope is equal to        Distance of y-values

                                                              ________________

                                                               Distance of X-Values

That represents a fraction.

Hope this helped and have a great day,

Step-by-step explanation:

A

note from the table that the cost increases by $15 for each package, then this is the multiplier for the cost.

let n be the number of packages , then

cost = 15n

B

to find the cost of 7 packages , substitute n = 7 into the rule

cost = 15 × 7 = $105
