Mean and median of 47,49,54,50,48,47,55

median- 49

mean- 50

Steps: find median order the numbers from least to greats the number in the middle is your median if there are two numbers in the middle you add the two numbers then divide by 2

find mean add all the numbers then divide by how many numbers there in this case you divide by 7

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)
