Well ,How to put a question on please help ASAP​

congrats, you just put a question

anyways have a nice day and thanks for the point

How did you post this question if you don't no how to post a question on lol.

Step-by-step explanation:

You press the button that say's ask question and you ask what ever question you want to, but don't post wired stuff please.

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)
