The following list has a median of 43. What would be the new median if 21 was added to the list? 31, 48, 50, 23, 28, 52, 57, 38, 56, 27

34.5

Step-by-step explanation:

21,23,27,28, 31, 38, 48, 50, 52, 57

31+38=69

69/2=34.5

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)
