Select the locations on the number line to plot the points −2/12 and 6/12 .

The given number are

and

Observe that each number can be simplify at follows

So, the number we need to place are and .

The image attached shows the number line with these numbers. The negative number must be on the left side of the zero, and the positve number must be on the right side of the zero.

Remeber that 3/6 is equal to 1/2. Also, when we graph fractions, we can just graph number with the same denominator, that way we would place each fraction in the right order.

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)
