The population of a certain species of bird in a region after t years can be modeled by the function , where t ≥ 0. Graph the function for 0 ≤ t ≤ 500

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)

step-by-step explanation:

x+14

step-by-step explanation:

a .4y4

hope this !

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
