How do you do this need right away

I’m writing this quick so it won’t be a full answer but will give you the idea. So what you gonna want to do is divide that confusing shape into smaller figures. For example that circle at the top you’re gonna draw a line connecting those two spaces then we see that little indent by the 2 km in the middle draw a line straight across all the way towards the side that has 12 K now find areas of those three figures. I hope that makes sense.

Step-by-step explanation:

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)
