How do i do a horizontal number line to represent the set of even negative numbers from -9 to -1

Here's what I get.

Step-by-step explanation:

Even numbers are numbers that you can divide by 2, like 2, 4, 6,and 8.

Negative numbers like -2, -4, -6, and -8 are also even numbers, because you can divide them by 2.

So, draw a horizontal number line that runs from -9 to -1.

Neither -9 nor -1 is an even number, so highlight with a marker all the even numbers between -9 and -1. Erase all the remaining numbers.

You now have a horizontal number line representing the set of even negative numbers from -9 to -1.

It should look something like the diagram below.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
