Geometry: BTS 2019; Chapter 4; Section 4.5; Exercises 1 - 57; Question 4
Find the scale factor of the dilation. Then tell whether the dilation is a reduction or an enlargement.
I can't get the image but the original is 9 and the new is 24

it is an enlargement ( I know) and the scale factor is 2.6 (I think. I can't do it without the image)

Step-by-step explanation:

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)
