The length of a rectangle is 200 m. The diagonal measures 250 m. Use this information to find the values of the perimeter and area of the rectangle.

Step-by-step explanation:

width=

        =150 m

perimeter=(150+200)2

                =700 m

area=150(200)

       =30000 m²

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)
