5.83

Step-by-step explanation:

Try using the Pythagorean theorem as an adaptation of the distance formula.  Count the boxes on the graph to create a triangle using the line segment as the hypotenuse.  

5^2 + 3^2 = d^2

25 + 9 = d^2

d = 5.83

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)
